Cloudy Day at Brookside Gardens

Last weekend we went to Brookside Gardens to photograph hummingbirds. The garden area they frequent still had lots of blooms.

I photographed other parts of the area: some favorite sculptures,

A rabbit eating breakfast,

Mushrooms under the roses,

And at artsy shot of an orange flower with a spiral shaped bud.

The best observations of the morning were bumblebees nectar robbing. The bee makes a hole in the base of the flower and then drinks the nectar. The shape of the flower would be a tight squeeze for these bees. Still – this is a case where the bees are not acting as pollinators since they bypass the flower structures entirely.

But hummingbird photography was disappointing. The lighting was not as good as the previous visits and there were not as many birds coming to the flowers. I only managed 3 pictures worth sharing.

So – the nectar robbing saved the day!

A few minutes observing…a tree stump

During one of the training sessions for the Howard County Conservancy’s fall field trips, we stopped briefly near the chicken coop to talk about topics for the kindergarten and 1st grade hikes. There is a stump in the area that used to be mostly surrounded by other plants…hard to get close enough to look at closely. Now it is clear all around it and it’s possible to approach in from all sides.  It’s been decomposing long enough to have several examples of fungus that were enjoying the recent wet weather to grow rapidly. As I listened to the conversation around me – I spent a few minutes photographing parts of the stump.

A flat fungus with tiny water droplets – with the clip-on macro lens.

A jelly fungus that seemed to glow (also with the clip-on macro).

And a picture with and without the macro lens that was a fungus that reminded me of mineral deposits in caves!

Sometimes pictures I take very quickly when I am rushed are ones I only take time to enjoy later…once I am home and have time to really look.

2018 Wings of Fancy Ends

Yesterday was the last day of Brookside Gardens’ Wings of Fancy butterfly exhibit. I volunteered for the last morning shift; taking in zucchini muffins to share with the other volunteers and staff. It started out slow for the butterflies and visitors; the day was cool and very cloudy. Then it warmed up a little and the sun even came out.

I looked back through pictures I’ve taken in the exhibit -ones I’ve liked but not posted for one reason or another. I think if headlines for some of them:

A Birdwing resting – being harassed by a smaller butterfly

Three Queens

Sleeping late (butterflies roosting long past sunrise because it was so cloudy – mostly Longwings)

Pining to go outdoors (Blue Morpho)

Living jade (Malachite butterfly)

I put the rest into a slide show…to prolong the joy of the 2018 Wings of Fancy exhibit one more day. I’m already looking forward to next April when the 2019 version will open!

Paper Wasp

In one of my forays into my front flowerbed to check Monarch butterfly chrysalises, I noticed a wasp on a poke weed flower stalk. It was moving all over the stalk, investigating each open flower. I had my camera…and took a series of pictures. The pictures were easy enough to identify it as a Common Paper Wasp Polistes exclamans using the Maryland Biodiversity Project website. I learned from their database that it is a species of the southeastern US that appears to be expanding northward. I looked around for the nest but didn’t see one. We still have some time for the larvae to develop but as the nectar plants die back, only the young queens will remain – in a protected spot to over winter.

Enjoy the paper wasp acrobatics on the poke weed flowers slide show!

Monarchs of September

Back in August it seemed like we were seeing more Monarch butterflies that at any time during the summer. They seemed to be everywhere. And they were laying eggs.

View fullsize

Toward the end of the month, there were large caterpillars and smaller ones too.

View fullsize

View fullsize

View fullsize

Then – I only found large caterpillars

And the chrysalises. Some still looked like jade pendants and others were already beginning to become clear – the monarchy colors coming through.

The elementary school that I delivered chrysalises and caterpillars too had their first butterfly emerge last Tuesday – 11 to 12 days after the chrysalis was made. When they released it, the butterfly flew away to the south! Hopefully it is not waylaid along its journey by Hurricane Florence.

Just this week I have had two butterflies emerge and fly way. They were both on the same window frame – opposite corners. On Wednesday morning – the first one emerged and stayed near the empty chrysalis until it flew away.

The second one emerged on Thursday morning. It crawled up onto face of the lintel. It took several hours for it to fly away – perhaps because it was a cloudy day and the humidity was about 90%. It is clearly a male based on the dark nodes on the lower part of the wings.

With all the diseases monarchs have these days – there have been disappointments too…at both the caterpillar stage and the butterfly. I’ve observed deformed butterflies probably caused by the parisite  Ophryocystis Elektroscirrha (OE) – and lethargic, shriveled caterpillars probably from Pseudomonas bacteria (aptly named ‘Black Death’)…so having an apparently healthy butterfly emerge is something I need to keep trying to help the Monarch butterflies! It’s a lot harder to raise healthy Monarchs now than it was back in the 1990s.

Butterfly Macro

When I use my phone for photography I resist using the zoom (since there is not optical zoom available…only digital) and just try to get close to what I want to photograph. Sometimes that it enough – like these to pictures of small Monarch caterpillars in my front flowerbed. They are still small enough that the black bands are dominating the yellow ones!

The clip-on macro lens is something I use frequently too. It requires getting even closer and a steady hand to focus. The touch samples at the Brookside Gardens Wings of Fancy  Discovery Station provided an excellent opportunity to take a macro look at butterfly wings.

The clear wing has a small patch of white scales but otherwise the wing is membrane stretched on a copper colored structure.

The blue morphos show the variation in blue from the incident of light even at the macro level. It is just barely possible to make out individual scales with the macro lens.

Cicada Identification

I photographed two cicadas in August. When I found the second one at home I had more time and took more pictures. I realized that I probably had enough different views that I should try to identify it. I knew it wasn’t a periodical cicada (one of the 13 or 17 year life cycle species) because it didn’t have red eyes.

I looked more closely at the markings and did some research using the Maryland Biodiversity Project website…and found it: Swamp Cicada – Neotibicen tibicen. The description they give fits perfectly: “Field marks include bright green in the wings, the white ventral area, greenish legs, and green patches on the head.”

I decided to return to the few pictures I took of the first one I photographed. There were fewer pictures because I was in the field with summer campers. Still – it is clearly Linne’s Cicada – Neotibicen linnei.

With this little success – I am motivated to try more often to identify what I manage to photograph…the challenge being to get quality photos from as many perspectives as possible!

Monarch Buddy

I started preparing for being a Monarch Buddy the week before school started (post about the prep here). By the time I delivered the larvae and leaves to the school at the end of the second day of school, I’d had further adventures.

The monarch egg that I’d gotten from the school garden on August 31st, hatched on September 3rd! I was checking it so frequently that I managed to take a picture before it ate its egg case! Compare the size of the caterpillar and its egg case just above to the straight pin used to hold the original leaf to a fresh leaf.

Twenty-four hours later the tiny caterpillar had eaten some holes on the fresh milkweed leaf and had visible stripes. It was still very tiny when it went to the school.

Wednesday morning, I had 2 of the 4 caterpillars making chrysalises. I was panicked because I wanted the school to have at least three caterpillars and I had only 2 (and 3 chrysalises).

I went outside and found no caterpillars – just lots of chrysalises. Then – in the tender top leaves of a milkweed – I found a tiny caterpillar about the size of the one that had hatched on the 3rd. I was thrilled and quickly set up to take it to the school later in the day. I ended up with two very small caterpillars, one medium to large caterpillar, and 3 chrysalises….and a gallon Ziploc of milkweed leaves that – hopefully – will feed the caterpillars of a few days at the school.

It’s good to see that her observations are wide-spread…that it’s the ‘new normal’ and services provided by institutes need to evolve to support these students.

Longwood Gardens – Part IV

Of course – there is a lot more of Longwood Gardens outside that in the conservatory. We walked out of the conservatory a few minutes before the 11:15 presentation of ‘Fountains Then and Now’ – and found seats in the front row on the terrace in front of the conservatory. Last time we had visited the gardens, the fountains were being renovated so we savored that a lot of what we remembered is still there plus there are high jets of water from air canons and nozzles that move to make arcs of water than move with the music. Afterwards we walked down to see the fountains closer and looked back toward the conservatory from the terrace of the big fountain. Under that terrace they now have some history of the fountain machinery….a little bit about how they got the water pressure needed originally and today. Part of the gardens (the Tower and Eye of Water) was closed off in preparation for the fireworks that were schedule for the evening (sold out long before we decided to visit) so the only perspective I got of the tower was from afar.

Then it was time for lunch. The air temperature was much hotter when we emerged from the café. We enjoyed the dahlias – and bees.

The garlic chives in the demonstration garden were popular with the bees as well.

There was a funnel spider with a web full of water droplets.

We walked past the fountains again to the formal garden rooms. I noticed some stone walls and realized that they probably told the geology story of the place.

I always like the stairs with water in the Italian Garden…but it was so hot – with no breeze - by the time we were there that the shade and water did not restore draining energy.

We walked along a boardwalk in the meadow full of joe pye weed and goldenrod on the way back to the visitor center. We cooled off walking around the gift store before starting the drive home.

Monarch Buddy

The third grade science curriculum in our county starts with a module about life cycle and traits important to survival….using Monarch butterflies as an example. I signed up to assist one of the school close to where I live to have raise Monarch caterpillars in their classroom. That means helping to find eggs or caterpillars and a supply of milkweed for them to eat. School starts tomorrow and I’m as ready as I can be for my Monarch Buddy role.

I started preparing last Thursday by collecting a large caterpillar from the milkweed in front of my house. It continued eating all day Thursday and I learned how to handle the leaves and caterpillars in the large plastic cups with a coffee filter held in place with a rubber band covering the top.

The covering worked. The caterpillar climbed to the top on Friday – hung in the J shape – and made its chrysalis. It should still be in that stage when I take the 4 cups to the school on Wednesday afternoon.

On Friday, I visited the school and teacher and I looked at the small garden that has been planted several years ago. It hasn’t been maintained recently but the common milkweed and butterfly weed was doing great without any intervention. There were lots of Monarch caterpillars. We decided to leave the garden as is; the teachers will us it as an outdoor classroom for their students. We did harvest a leaf with a Monarch egg on it and I am trying to keep it moist so that they egg would hatch. It would great to have a tiny caterpillar for the children.

On Sunday morning I collected 3 caterpillars: two larger ones and a smaller caterpillar.

I hope that at least two of them will still be caterpillars on Wednesday afternoon….if not – I’ll have to look for other caterpillars on the milkweed. My goal is to have 3 caterpillars and some chrysalises. The challenge might be to find very small caterpillars!

I am using the monopod if I can anticipate going to 65x…since it’s too difficult to compost the picture otherwise. I might eventually give in and use a tripod although not when I am going to be moving about. Lugging a tripod is never going to be something I want to do!

Enjoy the show!

Brookside Hummingbirds

My husband and I made the effort to get to Brookside Gardens early enough last Saturday and Sunday for some hummingbird photography; I’d seen photographers at ‘the place’ before my shift at the butterfly exhibit. The hummingbirds come to the bed of cardinal flowers and salvias in the fragrance garden that is in bright sunlight in the morning. It was a good opportunity for me to experiment with my new camera. I set the camera for continuous shooting (as fast as it can go when the button is held down) and savored how much easier the viewfinder is when trying to follow fast moving birds. I was pleased with several sequences from Saturday.

On Sunday there were not as many birds, but I had learned to zoom a bit more…make the bird bigger in the frame

I was also luck enough to track a flying bird to the magnolia tree and get a still portrait!

My husband was taking pictures at the same time with a big lens and much more expensive camera. His camera does a better job of ‘freezing’ the wing motion than my point-and-shoot strategy. He caught the hummingbird in the magnolia with is beak open!

Ten Little Celebrations – August 2018

I thought August might be a slow month with the summer camps ending and nothing new starting….but the month developed….not hard at all to pick 10 little celebrations to highlight.

Solitary hike – Usually I hike with other people – most recently with summer campers. Hike my myself at Mt. Pleasant was a change-of-pace and something to celebrate. Getting a artsy picture of two butterflies on Joe Pye Weed with a clear blue sky background was the image to remember of the morning.

Surviving a long hike – Then there was the much longer hike with camper up and down…across a stream and along muddy paths. I celebrated when that hike was done!

Blue Jay feather – A special feather is always a celebration for me…and from several perspectives: finding one on the ground, photographing it, remembering my daughter’s feather collection when she was very young, and realizing that know what kind of bird it came from!

Weekend in State College – Deciding to take a weekend trip – spurt of the moment. And dodging the rain to enjoy every minute! Celebrating family.

Butterflies – August seems to be my peak month for butterflies roosting on me in the butterfly exhibit. It’s special every single time.

Hummingbirds – Last weekend my husband and I attempted to photograph hummingbirds at Brookside gardens for two mornings. We were reasonably successful (a post about our experience is coming) but we’ll both improve with more practice. The birds are fast movers. Both of us are celebrating the photographs we got with the birds in focus!

Blooming bananas – Seeing something familiar but in a little different stage of development….I’m celebrating being in the conservatory at the right time.

Rulers for 25 cents – I celebrated that several stores in our area had wooden rulers for 26 cents. That’s inexpensive enough I can have my own supply for field trips with children just learning to measure sizes of what we find on our hikes.

Dragonflies – I haven’t found dragonflies in the wheel formation (mating) but I did find two at our neighborhood storm water management pond that were half way there! I celebrated the photographic opportunity and an still looking for the wheel.

Sweet potato leaves – Yummy sweet potato leaves. Our Community Supported Agriculture must have harvested part of the sweet potato crop in August so we got leaves in one of our shares this month. I hope there are still some left for later since we normally get them in late September. They are probably my favorite salad green….and I get them a couple of weeks a year….so worthy of celebration when they are available.

Butterflies at Brookside Gardens

August was a good month for butterflies at Brookside Gardens – both in the conservatory and outdoors in the gardens. Volunteering allows me to visit the Wings of Fancy exhibit and bring guests when I’m not ‘on shift;’ I get there just as the conservatory opens to indulge in some butterfly photography.

I challenge myself to capture eyes, proboscis, palpi, and antennae for as many butterflies as possible.

The stars for August were the big moths. There were male and female Atlas moths – kept separately so they couldn’t mate and lay eggs everywhere in the conservatory creating a containment problem. The males are much smaller than the females and the shape of the scale-less (clear) portions of the wing are different. In the pictures the male’s antennae are forward from the head…both females have antennae positioned back over their heads.

The other big moth was the Africa Moon Moth which looks very similar to our North American Luna Moth.

The Wings of Fancy exhibit runs until September 16….so a few more weeks to enjoy the butterflies in the conservatory.

Hopefully lighting will get some attention too….move away from the current dominance of blue tinged light for all times of the day and night.

BBC - Future - Are forgotten crops the future of food? – I have enjoyed the increase varieties of veggies I get from the CSA…and hope that we can further expand the food crops we utilize – for our health and to build more resilience into our food system which now is vulnerable because of the small number of plants and animals that we rely on.

Reverse Power Flow: How Solar + Batteries Shift Electric Grid Decision Making from Utilities to Consumers (In Depth) | CleanTechnica – I’ve started to wonder when the tipping point will occur – when there will be a mass economic defection by consumers away from big electric utilities. With small-scale solar ramping up to 20% of the new power plant capacity in the last 4 quarters and more people added energy storage to their solar arrays – maybe it is starting. It’s a fundamental shift for everyone. Maybe now is not the time to invest in utility companies unless they are buying in to that shift.

Brookside Wings of Fancy Caterpillars – August 2018

The caterpillars at Brookside Gardens Wings of Fancy exhibit are maturing….getting ready for cooler temperatures. On the walk up the ticket taker table, the last of the milkweed tussock moth caterpillars are finishing their leaves and pupating. A large number had to be moved to milkweed plants further from the caterpillar house so that the Monarch caterpillars would be on view to the visitors waiting to enter the caterpillar house of the exhibit.

The caterpillar house in August featured a white case (for the saddleback caterpillars) and then places for 3 pots (starring cecropia moth and monarch butterfly caterpillars).

The saddleback caterpillars grew bigger in August. I talked to at least two people that has been stung by them in their gardens!

The cecropia moth caterpillars made cocoons one my one over the course of the month. Yesterday there was only one caterpillar left on the black cherry – and it had been the runt of the caterpillars from the beginning; it’s catching up now.

There is a spicebush tree in a pot next to the black cherry where the caterpillars have moved to make their cocoons.

The monarch caterpillars have been the most fun to watch. I was in the caterpillar house once just after a caterpillar shed its skin.

They alternate between resting and eating….mostly eating.

View fullsize

When they are big enough to pupate, they try to leave the host plant. One started the walk-about when I was volunteering in the caterpillar house (round and round the pot looking for a way off) and we moved it to a portable mesh cube where it made its J and then chrysalis.

Outside there were many Monarch chrysalises on the plants and the structure of the caterpillar house. They always look like jade pendants to me.
