what is this beetle?
Nice website! These guys are on a Virginia Creeper vine in Southern Ontario, Canada. There are a whole bunch of them. At dusk there are a lot flying around the tops of some of the trees. I’m guessing they’re responsible for all the holes in the plant leaves. Any idea what they are? Thanks. Take care,

Hi Cory,
Japanese Beetles were accidentally introduced to North America in 1916. There are now a serious agricultural pest throughout the east. They will eat many plants and are very fond of roses, primroses, rose of sharon and grapes.

I live in the Central Northern part of Ontario near the shore of Georgian Bay in a small town called Waubaushene. I found these two beetles mating on my Sage plant this morning and cannot identify them. I have never seen anything like these before. I have included one picture of a ruler beside them to show you the size, but the quality is not as good—it’s just too darn hard to hold a ruler in one hand while pulling back the leaves with the same hand and hold a camera in the other hand steady enough to take a good picture. I was wondering/hoping you would know what they are. Thanks

Hi Gloria,
Except for the coloration, these beetles look like Grapevine Beetles, Pelidnota punctata. Grapevine Beetles are yellow in color. We did some research, and the Audubon Guide lists the coloration as “dull reddish brown to brownish yellow above with 2 black dots on the sides of pronotum and 3 black dots on side of each elytron. Top of head, scutellum, and underside blackish, tinged with green. We are believe these are just a red variation of the Grapevine Beetle. When Eric Eaton returns, we will get his opinion. Watch the website for an update.

japanese beetles
Last year I promised you a picture of a Japanese Beetle, as they normally frequent my garden. Well, last year there were none. This year I think I caught a Japanese Beetle family reunion. The photos were taken in Northwest Ohio on 7/6/2006.

Hi John,
Thank you for sending in this wonderful photo of the scourge of eastern gardeners. Mom currently has Japanese Beetle problems with her roses and primroses near Youngstown Ohio.

bugs from trip to Slovak Paradise
we have found these two beetles in Slovakia Paradise, could you please write some information about them, we are looking forward specially for information about this strange thing (cocoon,egg maybe) on back side of big beetle. We spend over two hours observing this beetle, she brougth out and in this cocoon, but nothing happend at the end. Female fall asleep :-).

Hi Kris,
Your first beetle is one of the Prionid Borers in the Subfamily Prioninae, but we are not sure of the species. This female is swollen with eggs and the ovipositor was was being “unsheathed” into the position for egg laying. The beetle would use the ovipositor to deposit eggs beneath the surface of bark on trees. Your second beetle is a Bee-Mimic Flower Scarab in the Tribe Trichiini.

Bug Love Photo!
I just have to say that I LOVE your site. I noticed you put up a “bug love” section… I have a photo to contribute. This is a photo I took of two mating beetles at the Seattle Zoo. I actually took a photo of the entire beetle exhibit, but didn’t notice THESE two going at it until after I got home and took a closer look at the photos. So I cropped the large photo down to include just the two lovers for your bug love page. However, I didn’t write down the name of the beetles from the exhibit.. and forgot what species they were.

Hi Brenda,
What a nice image to begin the first day of spring. We are relatively certain one of our readers will be able to provide a name for your amorous exotic Scarab Beetles.

another beetle
Found about 50 of these Junebug type beetles hatching in my large tub of compost dirt this fall. They are about the size of a Junebug but a bit more flat. Anything for our garden to worry about here? We are in SE Texas. Just love your site but can not even fathom the amount of work it takes to maintain it so well. You are doing a great job!

Thanks for the compliment. This is a Bumble Flower Beetle, Euphoria inda. The larvae are often associated with rotting wood, decaying vegetation, and dung, so the compost pile is the perfect breeding gound. You probably witnessed a mass metamorphosis. Adults visit flowers for pollen and nectar, and occasionally do damage to the blossoms.
