Hello. I found this couple on one of my roses last week. They stayed there over twenty minutes, and then flew away still in their embrace. Probably annoyed by me. They were pretty small (perhaps 1/4 inch), and I’m not sure I’m seen this type of fly before.

Mating Fruit Flies, we believe

Hi Barbara,
We believe these are Fruit Flies in the family Tephritidae, which is represented on BugGuide.  The closest match seems to be the genus
Campiglossa, which is represented by several species on BugGuide which notes:  “Adult females oviposit in flower heads of plant species in the family Asteraceae. The short, stout larva of Campiglossa live in the ovaries.
