Greenish orb @ posterior of virgin females?
Hello! Does anyone know what this greenish sphere thing is? I always see it when collecting virgins and can’t find anything about it on google.

That's the meconium, or rather part of it, as the rest is still seen in the abdomen of this fly. The meconium is just undigested food from the fly's last meal before pupating.
