Locust

[Kevin1]

Ok I've done a bit of research today on locusts. It's pretty interesting stuff. I'm actually fascinated with them now.
If you'd like the closest thing to the locust bred in europe(which is Schistocerca gregaria) you may want to check your backyard.

The genus is only found in the Americas except for the african desert locust(Schistocerca gregaria).
If you live in the right area you could catch your own to breed.
I'm going to attempt it.
Lucky for me there are at least 3 species of schistocerca in my local vicinity.
I haven't found much care info on them. But I hope this info is helpful to some of you.

Where did you find this out? Could you find anything about Colorado? Another worry is that most common grasshoppers only lay eggs in fall that wait through the winter and hatch in spring. Thats not very efficient for feeder purposes. Do you know of any that don't?

Well I jumped around from website to website.
One you may find interesting is Schistocerca Information Site
I couldn't find any info on if they can breed continually throughout the year.
Although I did find a species of band-winged grasshopper that I believe would be able to breed continuously. It's called the pallid-winged grasshopper.
I'm just going to try many different species next summer. There's quite a few in the u.s. that seem to be good candidates.

There aren't many in Colorado.

I believe Shistocerca nitens occurs in colorado.

[Tom Highum]

I dont think so but Shistocerca shoshone does

[Kevin1]

ah, your right I checked.
And about the Rocky mountain locust.
There are many, many species in the same genus as it.
If you already know of this site I apologize.
But I've been using http://bugguide.net/node/view/15740 quite a bit lately.
And here's another I've been using quite a bit.
