Luna Moths

/

There was a pause between my taking the last 4 luna moth caterpillars to the Butterfly House  and Luna Moths beginning to emerge. I kept the cocoons that had been constructed in the first wave in the mesh cage so that when they emerged, I would not find them scattered around the ceiling of my office! Once they started, a few moths appeared every day and I still have cocoons (so there will be more). I eventually managed to get a sequence of a newly emerged to ‘ready to go’ moth. The wings are very compact when they first emerge, and not the characteristic creamy jade color. The females have a large abdomen and thinner (not as feathery) antennae. They all seem to climb upward as their wings begin to expand and change color. The long tails are not obvious at first. Most of the time they finish up on the top or upper side of the mesh cage.

 I experimented with photographing them…trying not to disturb them too much. The best pictures are from opening the cage during the day for a short time and reaching inside with my phone!

The first ones to emerge were males. After a day or so, there were both males and females in the cage…and mating occurred. I took a group to the Butterfly House for their display and for collection of the eggs laid on the side of the cage to be used for a program in August (the eggs will be hatching by then).

One morning I released 8 moths into my neighborhood. They were all grouped in the top of the cage when I went out to our front yard where there is a tree with low branches. One flew out of the cage and away. The other 7 I moved to the tree; some of them flew away for the tree right away. One flew from the tree to the grass…then away before I could move it back to the tree. I left 4 (two mating pairs) in the cage. It was just before sunrise, so I hope they found a good place to spend the day (and maybe for the females to lay eggs).

When I got back indoors, I discovered that a luna had emerged in a bin that contained the cocoons produced later in my caterpillar experience. The plastic bin is not a good place to emerge since the plastic is too slick for the moth to climb. I moved the moth to the cage and am moving the rest of the cocoons to the cage too!
