eggs on a parasite on a parasite?

eggs on a parasite on a parasite?
UC Santa Cruz Arboretum, Santa Cruz County, California, USA
December 15, 2007
Size: ~2mm (whole fly)
Caught this louse fly today on a golden crown sparrow I was banding. Examination under a microscope revealed huge crops of egg-like masses extending off the abdomen. When I zoomed in on the abdomen, I saw two things: some mite-like critters attached to it and some swollen mite-like critters that were what the "eggs" were actually attached to. If any one has any insights on this or interest in investigating further, I'd be happy to take some more sharper pictures. I was having trouble figuring out the camera focus on the microscope but I think I can improve if needed.

Epidermoptidae mites
Great photo of mites in the family Epidermoptidae hyperparasitic on a hippoboscid. Species of Myialges and Promyialges have females with this hyperparasitic life style - males and juveniles remain on the bird host. Female mites imbed in the fly abdomen with highly modified first legs. They attach their eggs in a cluster around the female. I see at least 3 female mites in the photo.

at long last!
Thanks for that, I can completely see the three females and eggs that you're talking about now. I knew if I was patient this site wouldn't let me down :)

Joe, Epidermoptidae is a new family for the guide
do you happen to have more photos of those? this is our only picture of this mite family, and we need it in the Acari section; in any case, please post a duplicate directly to this page

probably not.
I may have taken some others, but I'm pretty sure I posted the best (least blurry) picture I could find. I'll hunt around in my photo archives to be sure. Somewhere lost in my lab is probably a vial with the original specimen in it. If I ever find it I can take some more pictures of it.

Can you remind me how to post a duplicate on the Acari section? I couldn't figure it out.


go to the linked page and click the 'add image' command
then fill the form copying data from this image.

I did it. Let me know if I can do anything more. I'll be back on here if I find more pics and/or the original specimen.

awesome... thanks for the addition, Joe
