A Moth with Really Quick Reflexes

We have had quite a number of lepidoptera out recently.  We have quite an outbreak of red admirals, but others are quite common as well.  A day flying moth, which I think is the celery looper, Anagrapha falcifera, is also present in large numbers.

Here is a photo I took of it:

The moth was setting down when I snapped the photo. 

I take a lot of photographs of insects.  Usually, assuming I don’t move too fast, the subject is not spooked by what I do.  Even when I use a flash, the bug just sits there.

Every time I tripped the shutter on one of these moths, the subject would be gone when the mirror snapped back into place.  I use a 1/25o second shutter speed, but there is probably about a 1/30 second lag from when the shutter is tripped and when the picture is taken.  So the moth was reacting within about 1/30 second to what I did.

The panic could have been caused by visual cues, although it happened with and without the flash.  I think it was reacting to the sound of the mirror snapping up, however.

No matter what I did, I always got a photo of a moth in motion.  In each case, the moth was not flying when I tripped the shutter.

So I think this moth can hear.

And it does have really quick reflexes.
