Flies on summer squash - Ptecticus trivittatus

Flies on summer squash - Ptecticus trivittatus
Scott County, Virginia, USA
August 7, 2014
I cut up some overmmature summer squash for my chickens this morning, and a couple of hours later, dozens of these little flies were flying around the squash. A couple landed on the squash to mate, but most seemed content to just fly around. Any ID would be appreciated!

Yellow Soldier Fly
Thanks for your ID! I notice, upon googling, that these flies are also known as Yellow Soldier Flies. Do you know if you can raise them on compost like Black Soldier Flies (Hermetia illucens)?

 
Yes, they develop in rotting
Yes, they develop in rotting plant material. While illucens eats literally everything (it is used in organic waste disposal), Ptecticus develops also in my compost pile, but they clearly prefer rotten fruit... I guess they have a sweet tooth, or sweet mandibular...
I have seen Pecticus in many countries, and they were always flying around rotting fruit. Also the males come to rotten fruit, just to meet the females there...
Cheers

Fruit-eaters
That makes a lot of sense! I may have to collect some of the larvae to add to my black soldier fly bin and experiment. :-)

 
Good idea to play around with
Good idea to play around with them... I guess they are not as hardworking as Hermetia larvae....
