Assassin Bugs

[Trenor]

Wow, they've grown a lot! You have subadults there. You'll see adults in the next molt

Nice, I'm thinking of rehousing them soon. They are starting to outgrow their deli cup. If I want them to lay I'll need to include moist substrate right? Are there anyway to know if they are males/females?

In A. cristatus, the female is quite a bit larger than the male. She also has a rounder abdomen than the male.

I do not know if the same holds true for other assassins...

Cool, when they molt again I'll post some photos and maybe we can figure out what they are. Thanks for the info.

Unfortunately I don't know how to sex nymphs, but sexing adults is quite easy as long as you can flip them over to see their last segment

Female

Male

Thanks for the information. I'll wait for them to reach adulthood then I'll see what I have. Hopefully, I'll end up with a good mix.

The individual segments of the abdomen are more distinct on the male. There also appear to be more segments.

Well, they molted and I have rehoused them. I've still not got around to sexing them yet.

Here are a few quick photos from my phone. I'm going to have to take some with the Canon soon.

Good work!

Lucanus95 - Do you have any photos of your setups and colonies? Are all the ones commonly sold to hobbyist (reds, whites, horrids, etc) kept similarly?
I also recently started keeping a few and have been given such varied info.
