BUG LOVE Stilt-legged Flies (Resend #3)
The first time i sent this i wasn’t sure what they were, but have figured out what they are now! Location: my yard in Houston, Texas. These two were really being x-rated, i felt a bit uncomfortable taking their pic at times! I had never seen bugs mating and moving so much, very human like. Most bugs i have witnessed just sit there connected. I have many more bug pics i would love to share with you. I love your site!

Hi Tracy,
We are happy you were persistant and sent these images three times as it would have been a misfortune to not include them on our site. We believe the species is Taeniaptera trivittata as evidenced by BugGuide.

Strange Fly 3/4" long in Simi Valley, CA
Hi Bugman!
My husband and I are real fans of your site. We find it exceptionally user-friendly, and seeing multiple images of an insect really helps with identification.
This fly-thingie landed on a palm tree next to my head and did not budge for fifteen minutes while I photographed it, tried to find it on your web site, and then finally went out and caught it. It is currently laying on its back in my insect magnifying jar. Could it be a tachinid fly? Its wings are clear with black markings. Very truly yours,
Renee Fraser

Hi Renee,
Thanks for the compliment. We also noticed from your second email that you correctly identified your Tiger Bee Fly, Xenox tigrinus.

unknown critter
I live in Glen Burnie, MD and saw this bug on my back porch. I am not sure what it is, so I thought I would ask you. So, what is it? He looks pretty scary. He was found at night. Thanks.

Hi Erica,
We are being besieged with images of Prionid Beetles in several genera from coast to coast. Your trophey male is one of the most spectacular, the Tile-Horned Prionus, Prionus imbricornis. You can see more on BugGuide. We especially love your head-on view of his magnificent antennae.

What’s this bug
We are in Missouri, woke up to let the dog out and the yard was swarming with these. When I mean swarming I mean swarming. The entire yard, the neighbors yard as far as the eye could see they were everywhere. I left at about 9 am to take my daughter to camp. The entire subdivision was covered in them!! Any ideas? When we came back at about 10 there is significantly less of them but they are still out there. They are on the west side of the house only though not the east. Maybe they don’t like the sun? Thanks

Hi Nikki,
You have been graced with witnessing the mass emergence of a species of Mayfly in the order Ephemeroptera. Adults only live a few days, their sole purpose in life being to mate and provide food to a vasy aray of other creatures higher up the food chain, like birds, fish and predatory insects. Larval Mayflies are aquatic, and live near a water source. Mayflies also are unique in that their are two adult forms, the subimago and the reproductive adult, known as the imago. We are also including a comment letter we got on a previous posting. You have pictures of a sloughed off exoskeleton and an adult. Perhaps one of our more knowledgeable readers can clarify if the adult is an imago or reproductive adult. If you are far from the water source, we are confident this is a reproductive adult.

Hi Daniel,
I sent in the comment several days ago about the mayfly imago and subimago; I’m a fly fisherman, among other things, and the mayfly picture with the shed exoskeleton jumped out at me. Interestingly, fly fisherman call the subimago stage of mayflies “duns” and the imago stage “spinners”. These are British terms, and I don’t know why they picked those words. … Your website is interesting, informative and fun, all at the same time, and I read it regularly. Thanks for your help.

Clarification: (07/19/2008)
Hi Daniel,
The picture of the adult mayfly from Missouri posted on July 16 is almost surely that of an imago rather than a subimago: the wings are clear, the tails are very long, and there is a shed exoskeleton. Mayfly subimagos typically have cloudy wings and relatively short tails, although no doubt there are exceptions to the rule. This insect is probably a species of the genus Tricorythodes. Fly fishermen refer to them collectively as “tricos”. They’re tiny, and it’s a challenge to tie a fly to imitate them and to fish it successfully. Tricorythodes emergences typically occur at night or early in the morning and the subimagos rapidly metamorphose into imagos; they mate, lay eggs, and die and it’s all over by noon.

Found these two while in Japan
Just wanted to know what kind of bugs these are. The first pair were “getting it on” in the middle of a path that ran through a city park in Tokyo. The caterpillar kind of freaked me out but it’s beautiful. Feel free to use the picture on your site if you wish. THANKS!

These are mating Carrion Beetles in the family Silphidae. As their name implies, they feed on dead flesh in the larval stages and adults feed on fly maggots to ensure more of the rotting flesh will remain as a larval food, helping to eliminate food competition for the progeny.

I know, I know…
A male Dobson Fly….
After reading countless inquries on your website, I now know that THIS is a male Dobson Fly. But mine is bigger than most on your site. All the others say their flies are about 4 inches. I have my size 12 shoe next to mine. He was easily 6 inches long. And believe me… size does matter. The people at the campground were freaking out over this bug.

Hi Mike,
It is obvious by the cocky tone of your email that you want the size of your, um Dobsonfly acknowledged online, and we are happy to acquiesce. We are also somewhat convinced that this will now launch a “my Dobsonfly is bigger than yours” competition among our readership. Where is the photo that arrived last week with the measuring tape? Lost in the black hole that is our email account.
