Really Red

The other day I photographed an insect that had the brightest red color I think I have ever seen.


Turns out it is a sawfly–a type of wasp.     Its caterpillar-like larvae eats poison ivy.


Its name is Arge humeralis.

    At last! A benefit of poison ivy.

    Do the caterpillars eat anything besides poison ivy?
