Can You Identify This Caterpillar?
Hi Bugman!
We have a butterfly garden, and I was just surprised to discover about 20 of these hairy orange, black and white caterpillars feeding on some plants out there. They’re small as caterpillars go — about 3/4″. I tried to find some like these on the internet, and I couldn’t, but in the course of trying I did find my way to your great website. Naturally, I’m curious to what these are (and I don’t plan to hurt or move them). Can you assist us in identifying them?

Of course we can Cathy,
You have Milkweed Moth Caterpillars, Euchaetias egle. The caterpillar is distinctive and unforgettable. This is a common insect, ranging from the Atlantic to the Mississippi and beyond. The caterpillars feed on plants in the milkweed family. The adult moth is creamy white-winged tiger moth with a yellow body. The body has black spots.

Hello Bugman,
My wife found this really awesome caterpillar a few days ago on her Gerber Daisies. I have been looking all over the Internet trying to identify it, when I stumbled across you site. It looks like someone has asked you about a particular “Saddleback Caterpillar”, and that seems to fit the description of the picture I’m sending you now. Is that what this is? Thanks for your help!

Hi Gray,
Yes, indeed, you have a Saddleback Caterpillar, Sibine stimulea. Beware those poisonous spines. They can cause quite a bit or irritation. Holland writes: “Nettles are not to be compared in stinging power to the armament of this beautifully colored larva.” Thanks for the photo and I’m so glad our site was helpful.

What is this bug?
I have hordes of this bug nesting in my patio which is made of stone blocks. They are going in the cracks and are huge! They never bother us but I am concerned that they could be destructive in some way. I have seen them taking green “grasshoppers” in with them. Sometimes they hover over the cracks between the patio tiles and then lower themselves into the ground. The one in the picture is about 1.25” long but I have seen smaller ones also. I forgot to tell you I live in Michigan and we have been seeing this bug for a good month or two. My dog keeps chasing them and occasionally catches one. They don’t seem to try and go after him when he antagonizes them. If it is a common flying insect, is there some kind of "bug killer" that won’t be harmful to my dog?
Thanks in advance,
Sherry Obershea

Hi Sherry,
You killed Sphex pennsylvanica, the Great Black Wasp. They are hunters of katydids, and they nest singly in burrows in the soil, not in mud nests. They are very non-aggressive. They are actually beneficial in keeping the destructive insect population down. You should learn to coexist.

Large yellow beetle
Bug Man,
My four year old son found this bug while camping… he quickly became attached to it and played with it for most of the morning! (a budding entomologist??); unfortunately the close up photo did not come out very clear. It was approx 1 inch long, bright yellow and unlike anything I’ve seen around here (central Saskatchewan , Canada ). The bottom was furry, much like the “Watermelon Bug” on your beetle page – though not striped. It had large legs that it used to help right itself when flipped on its back. Quite entertaining for the crowd of kids it attracted. A lady on the beach thought it was a “Japanese Dung Beetle” which she claimed to have encountered while farming cotton in the southern US – I’ve looked up pictures and this does not seem to be the case. Assistance with identification appreciated.

Hi Guy,
Identification is difficult because of the blurriness of the image. We sharpened it as much as possible, and believe it is a member of the genus Cotalpa. Here is a link with some good beetle photos, including Cotalpa lanigera and Cotalpa consobrina.

I was wondering if you could tell me what the attached bug is. We are in our late 50’s and have never seen this bug before. It is on our morning glory vines in Oklahoma. The gold spots are very bright.
Thanks for any information.

Hi Gary,
You have a photo of a Mottled Tortoise Beetle, Deloyala guttata. The species is often found on the foilage of Morning Glories. They are also called Gold Beetles by some people.
