Mantidfly - Dicromantispa sayi

Mantidfly - Dicromantispa sayi
Stow, Middlesex County, Massachusetts, USA
August 7, 2004
Size: ~15mm
I had collected some dragonfly exuvia and put them in a plastic container, and about a month later I opened the container, and found this mantidfly. Aparently the egg or larva was on the ode exuvia, and hatched out inside the container.

Brown form D. sayi
It's a good match with the picture in Marshall's book (1) page 255. He says it's a rare mantisfly that comes in yellow and brown color forms.

size?
I saw my first one of these last year and was surprised at how small it was - less than 10 mm. I had expected something big, like a praying mantis; maybe it was a young one?

Size varies.
Mantispids are predators of spider eggs, and the size of the adult depends on what quantity of food it got as a larva. So, different individuals can vary dramatically in size.
