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
thanks
Richard

Thick Legged Flower Beetle

Dear Steve,
Thanks for sending in your image of a Thick Legged Flower Beetle,
Oedemera nobilis. When the lighting is correct, the Thick Legged Flower Beetle appears a beautiful, metallic green color.  According to Bug Life:  “The thick-legged flower beetle is commonly seen on the flowers of ox-eye daisies and other open-structured flowers. They are a common occurrence in gardens in the South of England.”

Leather Jacket

Dear Michael,
This sure looks to us like the larva of a Crane Fly in the family Tipulidae, and you can compare your individual to images posted to Trout Nut, an anglers’ website.  Here is a BugGuide image.  We first read the common name Leather Jacket for Crane Fly larvae in Insects of the Los Angeles Basin by Charles Hogue.  Though it somewhat resembles the “graboids” from Tremors (see Monster Legacy) we assure you the Crane Fly larva is perfectly harmless.

Purple Small Headed Fly

Dear ?,
We are very thrilled to have received your query with a Facebook image of
Lasia purpurata, a Small Headed Fly in the family Acroceridae.  This is the fourth submission of this species we have received, the first being in 2005 and that sighting of this rare species with a limited range caused quite a stir.  We have always been amused that this species, which always appears and is described as being green, is commonly called the Purple Small Headed Fly.  That common name is used on the Arthropod Museum where it states:  “In 1933, Harvard University entomologist Joseph Bequaert described Lasia purpurata from a large, pilose, metallic blue fly with strong purple reflections that was collected in Oklahoma. Adults are often found feeding on nectar with their long proboscides inserted in flowers of butterfly weed, Asclepias tuberosa. This species is now known to occur also in Arkansas and Texas. While little is known of the biology of this particular species, we do have some understanding of general family biology. Larvae of all biologically known species are internal parasitoids of spiders. Large numbers of eggs are deposited in the vicinity of host spiders. Most species have planidium-like first instar larvae, that is to say they are strongly sclerotized and have spine-like locomotory processes. These young larvae are capable of crawling and jumping in search of spider hosts. Upon finding hosts they burrow though the integument and migrate to the spiders’ book lungs, where they can breathe outside air as they remain in diapause for several months to several years. Larvae of the subfamily Panopinae, to which Lasia belongs, have long second stadia and 4-5 day third stadia. In 1958, William Baerg, retired head of the Department of Entomology at the University of Arkansas and world renowned tarantula expert, reported that acrocerid flies, probably Lasia purpurata, sometimes attack Arkansas tarantulas. Female tarantulas produced 4-6 of these dipterous parasites. The parasites emerged from the tarantulas’ book lungs as larvae, and the tarantulas soon died. At Pea Ridge, most tarantulas appeared to be infested. The parasites emerged from mid April to mid May.”

Thank you! Yea a little after sending this email someone found the bug on your site. Cool little find!

Your letter to the bugman :  This bug was on my car today and I found it sooo neat! I’ve never seen something like this before! It body from head to tail? Butt? Ending? Was about at inch at most. I didn’t get to see it fly but it almost looks like it has a second smaller set of wings under the large ones.

Larviform Female Firefly

Dear Lauren,
16 years ago we posted a similar looking image of a Firefly from Colorado that Arthur V. Evans (through Eric Eaton) identified as a pink female
Microphotus pecosensis. We believe you likely encountered the same species, and here is a BugGuide image for comparison.
