Entomology (Study of Bugs)/Large, Aggressive Flying Bug ..

Well I would like to speak on behalf of the so called witness.  We were driving up to Sudbury last summer and this huge black bug hit our windshield.  It was at least 2 inches wide and about 3 inches long.  It was black.  The impact and the realization that it was a bug startled me.

I have encounteredthis bug as well. I do think the man was exagerating about the size, however it is fairly large. The bug I encountered was about 2 inches long and 1 inch wide. It looked a lot like a horse fly except it was much larger. I took a picture with my phone and would be very happy to email it to whoever could tell me what this bug is.

Hi.  Doug - if I could add to KM's experience.  Last night I was at a local ballpark and I heard this buzzing zip past my head and accidently bounce into the facia of a nearby roof.  It was obviously stunned as it flew in circles for a brief moment and then flew straight down and landed on the bleachers beside a little girl who didn't hang around long.  My point is that KM's husband wasn't that far off in his description of this beetle-like thing.  It was at least 3 inches long (based on my index finger) but not quite the girth detailed but still large.  As it was stunned already, I collected it and put it in a glass jar with air holes and my son is attempting to identify it.  It was still alive the morning after but was clearly showing the affects of bouncing of the roof - could no longer fly and was having difficulty moving around.  I'm not sure if this is useful, however, if we can identify it, I will post a subsequent follow-up.  Hopt this helps.  PB

Actually, her Hubby's estimate in size isn't that far off. I've seen a large winged insect numerous times I'm still trying to identify. Large pincers and 3 inches or so long. It's body thick as my thumb. Dark in colour, however not "fuzzy". There is a bug around approximately that size. She's not mistaken.

Kirsty, I believe you....I just saw something of this description tonight. I just began some research to try to figure out what it was because it was something I had never seen. Any more info, please share.

I was out for a jog tonight in Brampton and when I slowed to a walk I noticed what I thought, at first, was a leaf on the side walk (it was nearing dusk). I went to kick it but instintively dodged to the other side of the side walk when I realized it had legs and a shiny back. It was approximately 3" long and maybe 1.5" wide. I made note of where it was and went inside to get my camera, but when I returned to the spot it was gone. I'd like to correct your statement... there are no "KNOWN" insects in Ontario that are that size... but there most definitely are big bugs to be found.

Check out the Giant Water Bug... common in north america, capable of flying, similar to a beetle but not fuzzy.

I wanted to pop in here and say that I also live in southern Ontario and saw the EXACT same thing you seem to be describing.  I have been searching all morning to try and find a picture of what i saw.  So far I've come up with nothing.

Its a lot of years ago now but your description of this insect sounds likes like one I encountered whilst staying in Tilbury, Ontario.

This was certainly 3 - 4 inches long, it was black and was shaped a bit like a cicada but with black wings. It was flying at me and my cousins whilst we were in a swimming pool!

I saw the SAME thing you described!! It landed on my leg with a thud, I heard it WAY before it got to me! The description matches exactly, the only thing I am unsure of is if it was fuzzy. It was dark when I encountered it. Have you found anything else that might identify this creature?! I am scared to go outside!

I've seen tonight to my astonishment, a flying bug  with large front antennas, but had additional claws positioned under the antennas, which contracted horizontally , similar to an earwigs claws, long black hairy body, shaped like a carrot, the tail being the smaller part, very large transparent wings, the wings reminded me very much of the wing on a regular fly, but enormous in size, it had short stubby legs, it seems to be flying blind, I happened to have a binder in my hands, I wanted to persuade it to go back outside, but it hanged on to the binder which holds 8.5" X 11" papers, my wife and I were surprised to see such a specimen, but being an engineer I remained composed to observe distinctions in its geometry and scale, it was easy to determine its length by comparing it to the binder, and my wife and I both agree it's length to be no less than 4 inches long, with an equally large wing span.

Experts please identify.

I expect too much time has elapsed for me to add a comment to the message I have just seen about the aggressive flying beetle, but the husband's description of the insect ad its behavior exactly matches my experience when such an insect flew into my apartment in Hong Kong and flew straight for me. Its body was about 4 inches long and its antennae were the same length. I always assumed it was a longhorn beetle. I was terrified and getting it out of the apartment was a nightmare I shall never forget.

I live in Sudbury, and these beetles are everywhere. They're disgusting and scary, and they bite hard taking big chunks of skin! I hate them, I'm terrified of them! Here us locals call them Pine beetles, but they're really (I'm pretty sure) Whitespotted Sawyer beetles. I researched them and this (the male in particular) are exactly what they look like:

Is this what you guys saw?

about 10 mins ago a long time friend was in my kitchen on the phone and heard a loud buzzing ,almost a tattoo gun sound he said..he looked around thinking it was a appliance.the person on the phone also heard the buzzing noise...he moved a wooden kitchen chair and the noise stopped,looked down and seen a rather large insect with wings that he said were transparent and it was moving...ihe normally isnt scared of bugs,so he sais, but he ran up to me and told me,i came to investigate and saw no bug..i moved appliances now we have this massive bug in our house and i just had to google.he saidhe said it wasnt fat but not skinny,about 2-3 inches long and black hoping that this bug isnt dangerous,we do have 2 children in our home..not sure if this helped your research..but any updates are good ones i guess..

I live in Houston Tx, obviously far from Ontario. I've had similar encounters with large mothlike insects and I've had very little luck identifying them. My wife was chased by a large dark moth, unlike anything she'd ever seen but our Wiemeraner chased it away. It was not a clumsy, "oops I didn't see you there", it was a charge, chase and a brief fight with the dog. My experience was with an insect that was about the size of a cock roach, but looked like a cross between a scorpion fly and a moth. It had 4 large wings and an abdomen like a dragonfly, but the actual stinger was that of a wasp, not curved like a scorpion fly. It had a brown fuzzy head and very large mothlike eyes. It flew with a very loud buzz. I don't doubt that our expert knows the indigenous insects of Ontario but to dismiss your encounter so readily as a case of mistaken identity out of absolute ignorance is pompous and uncalled for. People catch piranha in the Lake of the Ozarks every year and don't know why.

Where was this bug the same thing happened to me yesterday

??? an uneducated guess ???  could it have been a bat that had been disturbed into abnormal activity?

What about a warble fly? I remember seeing one as a kid years ago in southwestern Ontario. I think they tend to be near horse farms. They look like a giant black house fly.

Actually I have seen this fly up close and I have yet to see a picture of it. It resembles a fly in most of its look. Its rather timid and is about the size of a adult baby finger and 1.5 the width of your finger. its front mouth part doesn't show any visible parts. Wing span approx 5 inches, 2 wings. Best can describe its wing expanse is my cat tried to eat one and its wings clearly could be seen extended out on either side of her mouth. I rarely see this bug. But have seen it maybe 3 times, usually in summer months.

Ok I am almost sure this is what you saw.

I`ve been studying entomology for some 20 years, and I`ve been answering questions about insects on the net for nearly a decade now, and am familiar with virtually all groups of insects, both in North America and elsewhere. My greatest expertise is with bees, but I also work with wasps, flies, beetles, butterflies, and moths. If I don`t know the answer to a question, I can generally direct folks to a book or person who *can*. But no spider questions please, I don`t do arachnids.
