Separating B. lateralis nymphs

[ScorpDemon]

Outside of separating eggcases and hatching them in something else, how does everyone else separate the young for feeding or other purposes?

This is how I do it.
I have a sterilite tub thats about the same size or maybe a little smaller than a shoe box that has a groove around the edge on the bottom. I bump the climbing material on this and it dumps all sizes in there. I try to bump in places with more of the smaller ones so theres more babies than anything else. The babies all seem to find their way into the groove along the sides in the bottom. Then I take my "sucker jar"(will explain this in a moment) and suck up all the little ones I think I will need then return everyone else back to the colony.

Sucker Jar
To make this I took an empty flukers cricket food jar(any plastic jar will work) and drilled 2 holes in the lid as far away from each other as possible and cut some aquarium air tubing used for air stones, and put them in the holes I drilled and siliconed them in place. screw on the lid, suck through one piece of the tubing, use the other one to aim for the targeted roach and there you go.

Would love to hear how others do it as well. I'm open to easier ideas.

I use the "aspirator" method too, but put some netting over the one end of the tube you suck on. Keeps bugs out of your mouth... lol http://www.roseentomology.com/Insect_Aspirators.htm

there is a bulb that we use in the lab to draw on a pipette , that would be great as it will not force you to be a "sucker"

I know someone who sorts roaches out by size, by stacking containers with diferant size holes drilled in the bottom of them. The larger holes are in the top cantainer, but to small for the adults to go through. The holes then graduate acordingly as it goes down the stack. Fill the top container with roaches, and let set for a few min. The roaches will sort themselves out. Feed out what ever size you want.
