Zooming – October 2025

/

Seventeen pictures for October. They are mostly from Missouri and some left from September in the Chicago area.

I’m saving the fall foliage pictures until November; I suspect that the fall will be subdued because it has been so dry since mid-summer but I am on the lookout for opportunities to photograph the occasional spectacular tree!

Looking back at previous Octobers…

In 2024, I was enjoying Missouri Master Naturalist Core Training and an Identifying Woody Plants field class at Missouri State University.

In 2023, I made my first visits to the Shaw Nature Preserve and Butterfly House near St. Louis; there was a Chihuly glass exhibit in the Missouri Botanical Garden. My parents were still in their home, and I was enjoying birds in nearby Josey Ranch park.

In 2022, I travelled to London, Ontario with my daughter…passing through Detroit on the way. It was our first fall in Missouri.

In 2021, we made our last visit to Longwood Gardens from our home in Maryland and I photographed a lot of waterlilies. At the time, we didn’t realize it would be our last fall in Maryland.

In 2020, we were still doing most things virtually. Most of the pictures taken at home…a lot of birds at the feeders on our deck and colorful leaves. There was one trip to Conowingo Dam but the only picture in the post is of a stern looking Great Blue Heron.

Roston Butterfly House Finale 2025

/

The season for the Roston Butterfly House at the Springfield (MO) Botanical gardens ended the first weekend in October. I continued my weekly shifts.

On some of the cooler mornings in September, the caterpillars were the big show. Sometimes the skippers and hummingbird moths outside the house were more active. As the morning warmed, the butterflies in the house became more active and some seemed to enjoy sitting on people (including me)!

The large silkworm moths (cecropia, polyphemus, and luna) were not as available for display as during the summer months.

There was a very hungry tiger swallowtail caterpillar on a tulip poplar leaf; I made a short video.

My last shift was the Monday before the last weekend. The ‘stars’ of the shift were the Monarch butterflies (looking health and ready to migrate south), a black swallowtail caterpillar, and a luna moth (the last of the large species of silk moths we had to display).

I enjoy this type of volunteering…plant to do it again in 2026 and maybe do even more shifts!

Butterfly House – August 2025

/

So many things to see in the Botanical Garden and the Roston Native Butterfly House this month. There are plenty of native plants in bloom in the rain garden on the walk between the Botanical Center and the house….but I just take a quick look since I want a few minutes to get things cleaned up before turning the sign to ‘open.’

Sometimes we find butterflies that have died overnight. I took a picture of one before we put it in the small bin we keep for butterflies that have succumbed. Another morning I found the 4 parts of a cecropia moth’s wings scattered on the floor; maybe a mouse ate the body during the night?

I like to see butterflies getting nectar from flowers…but sometimes it is enough to see them ‘resting.’ There are often fresh zinnias for the butterflies – freshly cut from the Master Gardener area of the Botanical Gardens. And there is always something blooming in the house itself. I like the Zen of the place when there aren’t many people but there is always the magic of a child’s wonder seeing a butterfly in a way they haven’t before.

The caterpillar that was ‘new to me’ this month was a Zebra Swallowtail…large enough to make its chrysalis – picked up off the floor when it was trying to leave the plant!

The moths are easily photographed because they are not very active during the day. The Luna moth is my favorite….but the Polyphemus is beautiful too. They, along with the Cecropia, have large caterpillars that are always interesting to visitors.

Polyphemus Moth - Macro

/

I posted about the battered Polyphemus moth shortly after I found it. This past weekend, I spent some time photographing the moth at closer range than I could when it was alive. The hindwing is almost behind the forewing now. It’s easier to see the antennae are somewhat feather-like but not as big as a male’s antennae would be.

Turned over – some of the legs have already broken off. The abdomen is drying. It may be that the moth laid all the eggs she had before her death.

A close-up of the thorax and abdomen reveals scales that look a lot like hair.

The same is true of the wing.

I put the clip-on magnifying lens on my cell phone. The magnification shows scales although they appear to be much narrower that butterfly scales and don’t lay as flat.

I noticed that even though I was trying to be gentle – the antennae had broken off.

With additional magnification, the antennae seem to have joints. They may look somewhat like feathers but not when viewed closely. These are sensory organs.

Since the specimen was battered and had already lost some lower leg parts…and antennae – I decided to take a closer look at a hindwing separately. The wing was already brittle and breaking almost every time I touched it.

I decided to use a jeweler’s loupe rather than the clip.

The ‘eye’ structures on the wing are clear in the center (the green paper underneath the wing shows through). The scales still look hair-like much of the time…not as fitted together as the scales of a butterfly.

I found some pictures of Polyphemus moth scales from a microscopy magazine that look similar at the same magnification I was used…and then includes a more magnified view (figures 4 and 5).

Battered Moth

/

Earlier this week when I was heading out to a volunteer shift at Brookside Gardens’ Wings of Fancy exhibit, I noticed something moving at the base of the red oak tree near our mailbox. I got out of my car to see what it was. There was a large moth flapping around on the ground among the remnants of day lily plants. I took several pictures with my phone and continued to Brookside.

When I got there, the staff helped me identify what I’d seen: a Polyphemus moth (read about the species at Maryland Biodiversity Project and Wikipedia). It’s a female because it doesn’t have the feather-looking antennae. It looked very battered and it died sometime after I left. I collected it when I got home and have it in my freezer…trying to decide what to do with it.

The caterpillars require about 60 days to grow enough to make a cocoon to go through the winter…so this is going to be cutting it close for the eggs this female probably laid in our oak tree. Some of the leaves on our oak (a food plant of the caterpillars) are already beginning to turn reddish brown. None of the branches are low enough for me to see any of the caterpillars in action unfortunately. I’ll still be watching the tree hoping to see one as they grow larger.
