Now That's a Fly!

July 25, 2011

Oh, to go through life being called a "short fat fly." Such is the case with a specific tachinid fly (family Tachinidae, genus Gymnosoma), which we spotted on a coreopsis (aka tickseed) growing along a Fort Bragg cliff. It's an odd-looking fly. Its abdomen resembles a ladybug or lady beetle.

July 21, 2011

For at least three days, he visited our yard. He swooped over our fish pond and swimming pool and returned each time to perch on a tomato stake in the vegetable garden. We nicknamed him "Big Red." Big Red? Actually, a flame skimmer dragonfly (Libellula saturata), native to western North America.

July 19, 2011
By Kathy Keatley Garvey
Blue damselflies should be on "Dancing with Stars." Because, in many respects, they ARE the stars--the stars of the insect world. They're slender, delicate and beautiful dancers that look like blue-stick diamonds.
