Tephritid Fly
Mon 2011-08-22
A female Tephritid fly, probably Terellia serratulae (Diptera: Tephritidae) on a thistle.
Terellia longicauda is very similar but in the female the oviscapus is as long as the abdomen (the ovipositor itself is retracted into the abdomen). Terellia ruficauda is also similar but has dark markings on its wings.
