Hello Daniel
I have tried to Google and find out what this one is. Bu with little success. A friend told me she thinks it’s a horsefly. I Google orange horsefly but did not find anything like this. Although it does look a lot like some of them. Is it just a different type of horsefly?
Sorry about the little pic.. once again. Can only get so close with my mobile:-)

Possibly Longlegged Fly

Hi Rob,
We believe this might be a Longlegged Fly in the family Dolichopodidae.  It is not a Horse Fly.  According to Bugguide which covers only North American species, Longlegged Flies:  “vary in appearance and biology. Adults are medium to small slender flies normally with green, blue or copper metallic colored bodies and long legs. Their wings are clear or marked with darker areas towards the wing tips. Wing venation is characteristic.”

Hi guys,
Thought you might like this picture for your food chain pages. A tiny immature Dolomedes Instabilis has caught itself an Austrosciapus connexus, one of the Long Legged Flys. The fly is about 6mm long.

Water Spider eats Long Legged Fly

Hi Trevor,
We greatly appreciate that you take the time to identify your creatures prior to submitting photos, which makes posting your submissions so easy.  According to the Find a Spider Guide for the Spiders of Southern Queensland website,
Dolomedes instabilis is commonly called a Water Spider and their habitat is  “On the surface of still-water ponds; this spider has the ability to run on water surfaces and to form underwater retreats in large air bubbles, although some pisaurids make their webs in green leaves or small twigs of shrubs and may never have occasion to ‘walk on water.'”  The Brisbane Insect website has some wonderful photos and indicates the common name is Fishing Spider like its North American relatives.  The Brisbane Insect website also indicates the common name of Austrosciapus connexus is the Green Long Legged Fly.

Long-legged fly (Condylostylus sipho?)
Location: Naperville, IL
June 26, 2011 7:38 am
Dear Daniel~
I found this long-legged fly on a hydrangea leaf today. Although I am pretty sure it is of the genus Condylostylus, I am less certain of its species. Condylostylus longicornis wings are unmarked, and its legs are blacker. Condylostylus sipho has the wing markings of this specimen, as well as its yellow upper legs, but the body shape is different. So sorry to trouble you again, but I thought this was a really beautiful fly, and I understand they are predators of even smaller insects. Their legs resemble mosquitoes! Thank you very much!

Small Fly – Can you help, Daniel?

Hi Daniel,
I fished this little guy out of the bird bath the other day and managed to get a semi-decent shot of it while it was recovering. Do you know what type fly it is?

Long Legged Fly from Hawthorne California

Hi Anna,
Daniel would really like to use this photo in a powerpoint presentation on Southern California Flies.  It is a LongLegged Fly in the genus
Condylostylus which is well represented on BugGuideHere is some information from  BugGuide which tends to indicate that this is a beneficial genus of Flies:  “Food Mouthparts are for piercing (with a short proboscis). Adults and larvae prey on small insects; larvae of some species mine stems of grasses and other plants or live under bark
Life Cycle Larvae develop in wet to dry soil and pupate in cocoons made up of soil particles cemented together. Adults mate after elaborate and unique behavior, involving the males displaying their legs to the female.

Hi,
Of course it will be fine to use any of my photos in the powerpoint presentation.  I’m honored that you asked.
Anna

Green eyed bug with banded wing and body
Location: Downtown Sydney, Australia

Apparently feeding on nectar along with bees etc. Approx 12 mm long.
I thought that such a distinctive looking insect would be easy to identify but I can’t come close.
The images are definitely of the same bug.

Similar to the preceding inquiry, but seems to be no banding on the wings, and a less well defined banding to the body. Also head and eye configuration looks different. On the same bush at the same time.
Also about 12 mm long.

Longlegged Fly #2

Hi Mike,
Both of your insects are Longlegged Flies in the family Dolichopodidae
, and the Brisbane Insect website has some images of Australian species and it indicates:  “Adult Dolichopodid Flies feed on smaller soft body insects such as aphids.”  Your specimen with the banded wings and body appears very similar to Austrosciapus connexus, which is well represented on the Brisbane Insect website.  Information on the family as it relates to North American species may be found on BugGuide which indicates:  “Mouthparts are for piercing (with a short proboscis). Adults and larvae are predaceous on small insects. Although immatures of some species mine stems of grasses and other plants or live under bark of trees. Not much is known about larval feeding habits although some species are known to be predaceous.”  If the information that the adults are predators of Aphids is correct, you may have found them on the flowers searching for prey as opposed to feeding on nectar.

Longlegged Fly #1

Thank you, Daniel.
I think that I should have been able to find thees ones myself.
Mike.

Small Green Flies
May 29, 2010
This morning (May 29 2010) I have small metallic green flies/wasps in my vegetable garden. Not a swarm but I saw at least five. I haven’t looked for them elsewhere. (I only noticed these because I was taking a photo of a leaf problem on the potatoes.) The photo is on a potato plant, but they don’t discriminate. They are about 1/2″ long. One landed on me, too. They don’t startle easily. I live in the mountains of western Virginia. We’ve had alot of rain recently.

Long Legged Fly

Dear Hoping,
You wish has been granted.  This Long Legged Fly in the family Dolichopodidae is beneficial.  According to BugGuide:  “Adults and larvae are predaceous on small insects. Although immatures of some species mine stems of grasses and other plants or live under bark of trees. Not much is known about larval feeding habits although some species are known to be predaceous.
