Trapped Long Legged Flies

Dear bug fan,
While we doubt these are
Austrosciapus proximus, we agree that they are Long Legged Flies in the family Dolichopodidae.  They might be Condylostylus longicornis which are pictured on the Natural History of Orange County website.  It is unfortunate that they were trapped while attempting to control the invasive species Pegomya betae which is pictured on BugGuide.  You did not indicate if your traps were effective with the targeted pest species.

Long Legged Flies accidentally trapped

Thanks for your reply,
I was unaware of these little guys and sad that they were trapped, beautiful and apparently helpful, the traps did work quite well against the beet miners… really horrible destructive pests

Your letter to the bugman:  HELLO BUGMAN! I LOVE that this site hasn’t changed since i was in middle school like 8 years ago, god bless, we STAN consistency!! <3
anyways, I found this fly, its wing markings suggest fruit fly to me, but the metallic color says otherwise? And my entomology professor didnt understand why its thorax would be a different color than its abdomen? What do you think!? <3 <3

Long Legged Fly

Dear Julian,
Thanks so much for the great compliment, though we hope we have changed for the better over the years.  We have considerably more postings on our site now than we did then.  This is NOT a Fruit Fly.  It is a Long Legged Fly in the family Dolichopodidae, and it resembles this individual from the genus
Condylostylus that is pictured on BugGuide. It looks like it might be Condylostylus patibulatus which is pictured on BugGuide and which is known from New York as well as much of eastern North America.  According to BugGuide:  “Green body, black legs, black antennae, face with pale hairs, … In the Northeast, no other species has black legs and marked wings.”

Long Legged Fly

Dear Lady bug,
This is a Long Legged Fly in the family Dolichopodidae, and according to Ecologistics:  “Dolichopodidae generally are small flies with large, prominent eyes and a metallic cast to their appearance, though there is considerable variation among the species. Most have long legs, though some do not. In many species the males have unusually large genitalia which are taxonomically useful in identifying species. Most adults are predatory on other small animals, though some may scavenge or act as kleptoparasites of spiders or other predators.”  Thanks to images on Save Our Waterways Now, we believe your individual is
Austrosciapus connexus, and the site states that though there are other similar looking species:  “Austrosciapus connexus is the commonest of them, and found in backyards, gardens, as well as wilder country.”  The species is also pictured on the Brisbane Insect site.

I put fly traps up in backyard to help with flies around my dogs and I end up catching these bugs instead. I just want to make sure these are not mosquitos since my dogs and myself are outdoors in backyard often.  Thank you for any info you may give.

Long Legged Flies

Dear currious mom,
These Long Legged Flies in the family Dolichopodidae are beneficial predators in the garden, though they are only able to eat the smallest of prey.

Dear Bugman,
I try to keep abreast of what I am finding on my woody plants, and you have provided such excellent information in the past.  Please help me identify this metallic green insect.  It moved about very warily, and getting a photo was not easy.  Thanks for any assistance you are able to provide.

Long Legged Fly

Dear Constant Gardener,
This is a Long Legged Fly in the family Dolichopodidae, and based on the Natural History of Orange County site, we believe it is
Condylostylus longicornis.  The species is also pictured on BugGuide where it states the range is:  “California; North Carolina to Paraguay; Polyensia. Possibly the most widespread species of the genus.”  Of the family, BugGuide indicates:  “Mouthparts are for piercing (with a short proboscis). Adults and larvae prey on small insects.”  This is a beneficial predator that will help keep your plants free of Aphids and other small insects that are injurious to garden plants.

Long Legged Fly

Dear Geo,
We believe, but we are not certain, that this is a Long Legged Fly in the family Dolichopodidae, and it looks very close to a member of the genus
Condylostylus which is well represented on BugGuide.
