Another Tachinid Fly

A female Phasia hemiptera (Diptera: Tachinidae) on hemlock water dropwort (Oenanthe crocata).

A few days earlier I had seen a male Phasia hemiptera on this patch of flowers beside the top lake, but it flew off before I could get a photo of it.  On this walk I made a point of checking the same patch of flowers and came across this female.  I also saw another male but again it got way before I could photograph it.

Muscid Fly
