Camel crickets are most commonly found August to October under rotten logs, stones, mole hills, basements, and other dark, moist places. Adults are active at night. They eat decaying organic matter, including mushrooms, dead insects, fruits, flowers, and dung.

 

 

     
           
 
Description
 
 

Ceuthophilus is a genus of large or medium-sized crickets. Adult males are ½ to 1 long. Females are larger than males. The head is oval shaped and is bent downward between the forelegs. The antennae are tapered and longer than the body, usually 2 or more times as long as the body. The body is stout and has a distinctive hump-backed shape. It may be whitish, pale brown, or almost black, with contrasting mottled markings. The egg-laying structure (ovipositor) on females is blade-like and straight. The legs are long and slender. The fourth segment of the leg (tibia) is longer than the third segment (femur). The tibia of each back leg is thick and has more than four pairs of movable spines. There is no spine on the front or side (dorso-lateral) surface of the tibia of the front leg. All legs have four end segments (tarsi). The first tarsus is almost as long as the remaining tarsi together.mThere are no wings or hearing organs (tympani).

Femur

On insects and arachnids, the third, largest, most robust segment of the leg, coming immediately before the tibia. On humans, the thigh bone.

 

Ovipositor

A long needle-like tube on the abdomens of some female insects, used to inject eggs into soil or plant stems.

 

Tarsus

The last two to five sections of an insect’s leg, attached to the tibia; the foot. Plural: tarsi.

 

Tibia

The fourth segment of an insect leg, after the femur and before the tarsus (foot).

I came across your page while looking for information to identify a strange looking critter.

I am 49 years old and still in the same small rural farming community I grew up in. I have never seen one of these weird little critters. It is a camel cricket or spider cricket. I see on your distributing map that my area does not show them. I am in Kenyon, MN and it is confirmed that they are certainly here now. Great site. Keep up the good work.

About

Published on Jul 13, 2014

This is a male Cave Cricket (or Camel Cricket) we found in the bathroom today. Cave crickets lack wings, and have a distinctive hump and downward-facing face, very long antennae and long legs, which enable them to jump quite high and far. The males of this species cannot chirp like other species can. Like their name implies, they can often be found in caves (and have a hump), and like most crickets are nocturnal (which is why this guy keeps out of the sunlight in the video). They also prefer dark, damp, cool environments (like caves!), which is why it was in the house, the bathroom specifically. It has been averaging in the mid to high nineties (Fahrenheit) outside lately and hasn't rained in weeks. Plus Texas is still going through a severe drought for the past several years. Cave crickets can damage cloth instead a home, like carpets and drapes. They also will eat just about anything edible, from decaying plant matter to dog food. These insects can actually become a pest and invade dark, damp areas of a home, like a basement. This video is short but captures this neat-looking insect.

We live in the country, close to the Zumbro River. I have seen camel crickets in our basement once or twice a year over the last few years, and  being a nature lover, I capture them and set them free outside. This last one I discovered in our basement shower.
