Tachinid Fly

Dear Charlotte,
Our best guess upon first viewing your image is that this might be a Long Legged Fly in the family Dolichopodidae, but we could not conclusively find any matching images on BugGuide.  It also somewhat resembles this Root Maggot Fly in the family Anthomyiidae pictured on BugGuide.  We hope one of our readers will be able to assist with this identification.

Update:  April 21, 2018
Thanks so much to Cesar Crash of Insetologia who provided us a link to the Tachinid Fly
 Cholomyia inaequipes that is pictured on BugGuide.  According to BugGuide:  “Females seen on flowers, perhaps (?) taking nectar” and “Parasitoid of weevils (Conotrachelus). Males, at least, come to lights.”  We believe the submitted image is of a male and since it was found on a door handle, it might have been attracted by the porch light.

Your letter to the bugman:  Found this “giant mosquito” looking insect on a grape vine.  What is it? Is it beneficial?

Crane Fly

Dear Dave,
This is a Crane Fly, and in some parts of the country they are known as Skeeter Hawks.  They do not sting nor bite and they pose no threat to humans.  Beneficial is a tough term to describe in terms of insects.  Birds and other predators will eat Crane Flies, so they do fill an important link in the food chain.

Oriental Fruit Fly

Based on images posted to Wikimedia and Nucleus where it states “Host: Most fruits and fruiting vegetables” and “Highly significant economic damage”, we believe this is an Oriental Fruit Fly, Bactrocera dorsalis.  According to Featured Creatures, the Oriental Fruit Fly has been introduced to Hawaii and “The oriental fruit fly, Bactrocera dorsalis (Hendel), is a very destructive pest of fruit in areas where it occurs. It is native to large parts of tropical Asia, has become established over much of sub-Saharan Africa, and is often intercepted in the United States, sometimes triggering eradication programs.”

Your letter to the bugman:  I found several of these insects on the emerging leaves of a red currant.  Can you tell me what they are and whether they are innocuous or harmful?

March Fly

Dear Nancy,
We believe this is a Stiletto Fly in the family Therevidae, and according to BugGuide:  “Adults are nectar feeders; larvae prey on soil arthropods.”  Several species are pictured on Natural History of Orange County, but none looks exactly like your individual.  ResearchGate has some images of Australian Stiletto Flies that look similar to your individual.  We hope to get a second opinion on our identification.

Daniel,
Wow, that was fast!  I’m sure you’re right about the identification.
I do so much appreciate your interest and expertise.  And I gained more knowledge about my insect neighbors.
The fly larvae can eat all the soil arthropods they like from my garden!

Eric Eaton provides a correction:  March Fly
Daniel:
Sorry, I am “out of the office,” hence the delay in replying.  This is a dance fly, probably genus Empis.  Probably female, too.  Pretty common early spring flies in the Pacific coast states.

Ed. Note:  Once Eric Eaton provided us with a genus name, we did find this individual from Ireland posted to Alamy and this individual from California posted to BugGuide.

Daniel,
Well, that sounds a lot more peaceful than “stiletto fly”.  I either case I don’t have to worry about the larvae eating my currant plants.  It’s a real struggle saving them from the aphids in the spring. I’m so impressed that you and your colleagues would provide this service, which I have bookmarked and will recommend to all my friends in the gardening community here.

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.

Your letter to the bugman:  Hi,
I found this bug on my patio. At first I thought it was an ant, but its antenna seem too short. It doesn’t really look like pictures of termites that I’ve seen. It seems too small to be a wasp.  I would really appreciate it if you could give me some guidance as to what it might be! Thank you!

March Fly

Dear Alyssa,
This is a March Fly in the family Bibionidae, not an Ant.  March Flies often appear suddenly in large swarms, they remain a few days and then they are gone.  Your individual appears to be a big eyed male.  There is a species of March Fly that appears in such large numbers of mating pairs in Florida that they are called Love Bugs.  Because of the red legs, we believe this might be Bibio femoratus which is described on BugGuide as “Shining black, dense yellow hair, red femora” and it is found in “Most of North America, except Canadian arctic and Western USA.”  BugGuide data includes reported sightings Oklahoma, but not Texas, but that just means there have been no reports to BugGuide from Texas.
