Unidentified Caterpillar
I need help identifying this really neat caterpillar I found here in SW Michigan. It is about 2 1/2 inches long and seems somewhat similair to some larvea of the Antheraea family. I would like to try and raise it and was wondering if it needs to eat now and if so, what should I feed it?

Sorry Joanna,
The best we can do is agree it is one of the Giant Silkworm Moth caterpillars, Saturniidae. It somewhat resembles a cecropia moth and it somewhat resembles a cynthia moth, but it doesn’t look exactly like either. We will keep trying to positively identify it.

What an excellent and fun website! I thought you might be able to help me with two mystery bugs that have proven baffling. The first is a caterpillar I saw in the mountains of central Nepal. It was at about 2000 meters, in cleared but overgrown land. The caterpillar was about 6 and a half cm long, and as you can see below, quite colorful. For lack of a better term, I’ve nicknamed it the ‘Himalayan Dragon’. Any ideas what this dragon turned into later in life?

Hi Robbie,
Thanks for the photos of the exotica. They are a mystery to us as well. I can tell you with some degree of assurance, that the caterpillar will probably metamorphose into a moth and not a butterfly. It looks like it is some species of Tiger Moth or Tussock Moth, but we cannot be sure. We are content with the name Himalayan Dragon.

What type of spiders, with bumps on their backs?
Hello there,
When my mom first started putting some plants in her greenhouse earlier this year, We found a couple of small spiders, which appeared to have 2 horns / bumps on their backs… After the plants were done in the greenhouse, and we moved them out out, we thought the spiders left, but it seemed one moved around to the other side of the house, and a couple others appeared…
They’ve grown quite a bit, and were curious to what type of spiders they are? They are about 15 – 20 mm big…
Today I caught 2 flies for each of them, They were really quite fast at grabbing them and spinning them into a ball.
I tried to attach a couple of different angles of pictures I took, so you could see the bumps on its the back.
We live in Hanna, Alberta 🙂
Thanks, Zac

Hi Zac,
Sorry I don’t recognize your species, but I can tell you it is from the group known as Orb-Weavers. These spiders build a classicly shaped web and wait for prey. Keep feeding them flies and they will grow to maturity.

Please help me identify this bug.
I live in Salisbury, Maryland and found this bug in my house. I assume it’s a beetle, but am concerned it could be a roach. Just wanted to ease my mind. Thanks for your help.

Hi Deb,
Many of the Ground Beetles, Carabidae, are black with red legs. I can’t identify your exact species, but I can tell you that they are predaceous, and will kill other unwanted pests around the home and garden.
