Garden Bugs of August #2

Tachinidae - Tachnid Fly

From August into Fall, the Asters are humming with visitors. This is a Tachina sp., one of two spiky tachnid flies that were visiting this day. While seen here innocently feeding on nectar in the flowers, the tachnids have parasitoid larva, the eggs being laid on caterpillars and the resulting grubs feeding on the host’s innards.

      The tachinids – they do possess a kind of cool creepiness!
