This is not the best lit picture in the world but myself and my friend found it at 4am in our hotel room in Aguas Calientes, Peru, before walking up to Machu Picchu. I had heard it flying around our room the night before and thought that a small bird or bat had got in! The bug was about the size of my hand (about 15cm) and we found it on July 11th. I asked my Peruvian tour guide if he knew what it was but he shook his head in terror and swore in Peruvian. It remains a mystery…

Dobsonfly

Dear Eve,
This South American Dobsonfly has relatives in North America that are also quite large.  Despite his fierce appearance, this male Dobsonfly is perfectly harmless as his mandibles are not designed to bite.

Hi I found this bug resting on my deck railing yesterday. The ruler moved as I took the picture but it is over 4″ long, has wings that are tan, brown and black, beady black eyes and “pinchers”. I did not see it fly or land. An hour or so after I took the pictures it was resting on the vinyl siding of my house about three feet away. It was gone this morning. I am in Upstate NY about 45 miles north of Albany and about 20 miles west of Vermont border.

Male Dobsonfly

Dear Kathy,
Despite his fearsome appearance, this male Dobsonfly is perfectly harmless as his mandibles cannot pierce or bite human skin.  Though her mandibles are much less impressive looking, the female Dobsonfly is actually capable of biting if carelessly handled, and she might draw blood, but again, she is considered harmless.

Thank you so much! I have never heard of that insect but now am going to research it.

They are usually found near bodies of water.

came home at night, and the end of june. the bug was sitting off away from the light, almost in the shadows, has 4 wings, eyes on the side of the head, almost ant like pinchers, to very long feelers coming off the top above and towards the front of head. I do have a couple of more pics if need be

Female Dobsonfly

Though she is basically harmless, you might want to stay clear of the mandibles on this female Dobsonfly as she might deliver a painful pinch.

Hello,
We encountered this insect on walk near the Potomac river in Maryland. At first we thought it was a Praying Mantis, but looking at the photograph we are not certain.
Your help appreciated.

Hi.
I found this bug dead in an abandoned farmhouse in central new york in late may. The underside was a an orangey-brown color and I’ve never seen a bug like this in that area before. At first I thought it was a queen termite or something, vit that doesn’t seem to be the case. Do you guys have any clue to what this is?
Signature: – its very scary pls help

Hellgrammite

Hellgrammite

We are speculating that the farmhouse was near a stream or river.  This is a dessicated Hellgrammite, the larva of a Dobsonfly.  Both Hellgrammites and female Dobsonflies are known to bite, and they may draw blood with their powerful mandibles, but they are considered harmless, and Hellgrammites are prized bait for freshwater anglers.

Fishfly

Fishfly

Dear JMBama,
This is a Fishfly in the genus
Chauliodes, and we believe because of the BugGuide description of the Spring Fishfly, Chauliodes rastricornis: “Compare C. pectinicornis. Head and pronotum have dark markings on light brown background, as opposed to yellowish markings on dark brown background of C. pectinicornis” that you have a Summer Fishfly as your individual has yellow markings on the pronotum behind the head.  We are postdating your submission to go live in the future while we are away from the office for a spell in mid-June.
