Moved from Ornithomyinae.

Moved from Louse Flies.

raising homing pigeons I seen these or similar species often. They can run between the feathers at unbelievable speed and fly very fast if one is dislodged. Birds didn't like them much and I dusted them when it got bad. Perhaps a vector for West Nile Virus. Read an article ( which was very interesting, the green in the legs is blood.


Thanks, Gary. That webpage was very interesting. I've seen several hippoboscids while bird banding, but, like you said, their agility and speed of movement between feathers makes collection very difficult. describes a Hippoboscid, Pseudolynchia canariensis, the "Pigeon Fly"; could be the same or similar to the ones you found on your homing pigeons. Thanks again.

Very streamlined
Interesting creature. Thanks for posting.

concur... this is an interesting find!
