Hi Bugman.
We find one of these in our yard at least once a year around mid summer. We have lots of trees on our property…old oaks and pines.

An interrsting looking bug landed on our table and we’d love to know what it is.
It has six legs, yellow in colour with 6 black spots in three rows of two down the back. Around 3/4 of an inch long, we found it in central France.

Hi and thank you for providing this site. I’ve got some good pictures (I think) of a beatle. He had lunch with me on my deck today. I’ve looked at a ton of pictures trying to figure out who this little guy is but to no avail, so I have dubbed him Frank for the time being. Do you know Franks official name?

Oriental Beetle

Dear Erin,
We identified this Oriental Beetle,
Exomala orientalis, thanks to Arthur V. Evans excellent book Beetles of Eastern North America where it states:  “This immigrant species from Asia is now established from Maine south to Georgia, west to Wisconsin.”  According to BugGuide:  “adults emerge in late June and July.”

Not exactly sure what these are so I’m curious but I was taking a small hike with a friend and my dogs on the tiger Dunlop trail in Goderich Ontario. It’s a beach town but the parts of the trail we started to see them wasn’t close to water. We saw so many of these guys EVERYWHERE! They seemed as if they were decimating all of the plants as well? Seemed as if the concentration was mostly the wild fruit plants like the raspberries and grapes. It also seemed like they were always also in groups together like they are in the photo I took. Goderich Ontario is in Canada on Lake Huron. I think it’s classified as southwestern Ontario but I’m not certain.

Mating Japanese Beetles

Dear Thora,
These are Japanese Beetles, an Invasive Exotic species first introduced to North America over a hundred years ago.  As you observed, they feed on many different plants and they represent a scourge to many home gardeners, especially those with a fondness for growing roses.

Hmm that is interesting. This is the first year I’ve ever seen them. Thank you!!

I have standing water on my property that is there from rain, not spring feed, today while looking at the water, I noticed these flat brownish insects in the water, I don’t remember seeing these bugs before, I thought they might be leeches but every picture I googled of leeches showed them being black. Also these bugs have pitchers, please help, thank you,

Water Tiger and Tadpoles

Dear D. Clement,
This appears to be a predatory larva of an aquatic beetle, commonly called a Water Tiger.  It is surrounded by Tadpoles, and they are most likely its prey.
