Mallophora fautrix - female

Mallophora fautrix - Female
Santa Cruz River wash, Pima County, Arizona, USA
July 26, 2013
Size: 15 mm est.
An alert BugGuider (not me) noticed this individual ovipositing on a stem. Thanks for the ID.


What a wonderful image!
One of my favorite flies.

Moved from Bee Killers.

Not clear
What the egg load is inside this casing but certainly it is likely multiples of the overall small eggs. In the bigger Mallophora species in central Texas, the larvae apparently drop to the soil. I assume it is true in M. fautrix as well.

Thanks for the clarification, Herschel
Even so and even with a thin walled container, that seems like a whopping lot of material for a fly that size to be carrying around inside her.

I think
It foams up like shaving cream. But it is odd. I have never gotten to see this process in our local species.

Wow! What load of eggs!
