I can not identify this bug and have never seen one. Can you help.

Flower Longhorns: Strangalia luteicornis

Dear K. Varszegi,
We believe we have correctly identified your Flower Longhorns as
Strangalia luteicornis thanks to images posted to BugGuide.  According to BugGuide:  “Adults take nectar and/or pollen at flowers, are said to be especially fond of sumac” and “Larvae feed on decaying wood of several deciduous trees and woody vines. Adults attracted to UV light.”

Dear big man. This bug was about as big as my thumb. (An inch or so long) he flew onto an old plywood fish smoker. He (I’m going to assume gender) went on to make a weird noise, almost as though he was nibbled the wood.

Bald Faced Hornet

Dear Dog Lady,
This is a Bald Faced Hornet, and we first wanted to establish that they are reported from Alaska.  BugGuide has no reports from Alaska, but they are reported from across Canada, so we can deduce they are probably found in Alaska, but we confirmed that since they are listed on Insect Identification:  Bees, Ants, Wasps and Similar Insects of Alaska.  Your gender assumption is wrong.  Only female Bald Faced Hornets construct nests and care for young.  You are correct that she was nibbling wood.  Bald Faced Hornets chew wood into pulp that they use to construct a paper nest.  Bald Faced Hornets are social wasps that construct a nest that they will defend.  They are not normally aggressive toward humans, but anyone attempting to disturb a nest can probably count on getting stung.

Hi I woke up last night with something clinging to my neck swiped it off and in the morning kept getting bothered by this tenacious beast it had a very solid hold on my skin and clothing (so assume it has claw like feet) and was not overly excited until I took it out into the light in the glass then it seemed to go berserk to get out of the light. There is a green tinge to the legs, and wings fold flush to the body like an insect that would shed the wings ? Pictures are ‘lousy’ I know but any help would be great. There are sheep in the nearby fields.

Louse Fly

Dear Scott,
Your images are not ideal, but we believe you are correct that this is a Louse Fly in the family Hippoboscidae.

Hi Daniel many thanks my first encounter with one but no bites I think.
All the very best Scott

Hello
We were trying to find out what this was. We had thought it was somekind of hoverfly but we have never seen one so big.

Dark Giant Horse Fly

Dear Dawn,
This is a female Horse Fly,
Tabanus sudeticus, and we just posted images of a male.  Only female Horse Flies are blood-sucking biters, and they can be distinguished quickly from males by the spacing between their eyes.  Males do not have a space between their eyes.  According to Influential Points, the common name for this species is Dark Giant Horse Fly and the site states:  “The dark giant horsefly flies in July and August and commonly feeds on the blood of cattle and ponies. In Europe … Tabanus sudeticus flies from the end of June and through July and August. Krčmar (2005)  reports that it reaches its maximum abundance in third week of July. In Britain it mainly lives in boggy areas in the north and west, although it is also quite common in the New Forest. Tabanus sudeticus is distributed widely in northern Europe into Russia.”  According to iNaturalist:  “a species of biting horse-fly. It is the heaviest fly in Europe.”  According to the Nature Net Ranger’s Blog:  “This is Tabanus sudeticus, sometimes called the dark giant horsefly. It seems, oddly enough, that this impressive insect has not really got a commonly-accepted English name. It’s referred to in one place as the “dark behemothic horsefly”: a charmingly descriptive name, albeit a little cumbersome. Yes, it’s sitting on my finger and no it didn’t bite me. They can be up to 25mm long (that’s one inch) and 50mm across the wings – a massive fly and the largest dipteran in Europe (I think it was bigger! Having measured the Ranger’s finger, the fly could’ve been at least 30mm – The Cat). Horseflies are big, fast-flying creatures, and they will bite any big mammal, including humans. The bite is very painful, and as horseflies cut the skin when they bite (rather than pierce it), horsefly bites can take a long time to heal, and can cause infection. Unlike insects which surreptitiously puncture the skin with needle-like organs, horse flies have mandibles like tiny serrated scimitars, which they use to rip and slice flesh apart.”

Hi Daniel
Thank you for getting back to me, and for your detailed description, it is very helpful.
Best wishes
Dawn

Found this guy on a tomato tower in my garden this morning. He was kind enough to sit still long enough for me to run and get my camera.

Flame Skimmer

Dear J.C. Hunter,
We are very happy to post your beautiful image of a male Flame Skimmer.  They are described on BugGuide as:  “males bright orange with amber color in the wings covering half the width of the wing, out to the nodus, and all the way to the rear of the hind wing.”  Several weeks ago we missed the opportunity to capture an image of one that was perched on a dried twig near our fountain (currently containing water but in need of a new motor) because it flew when we returned with the camera.  Our offices in Los Angeles overlook a natural portion of the LA River, though it is about a mile away.  Neon Skimmers and/or Flame Skimmers are the only Dragonflies we regularly see in our hilltop location.

I’ve never seen a beetle like this one which prompted me to figure out it’s identity. I came outside and spotted it on the hood of my truck. He was patient while I took several photographs. Eventually he walked a couple feet across the hood and took off flying. His body was a little less than an inch long with antennae as long or longer than the body.

Whitespotted Sawyer

Dear Daniel,
This is a Whitespotted Sawyer,
Monochamus scutellatus, and according to BugGuide:  “Similar to others of its genus, but scutellum white. (Scutellum is the little triangle at the front of the elytra, or wing covers.)”  The white scutellum is clearly visible in your image.
