Roaches know there siblings?

[joshuai]

hello i have a large colony of feeder roaches. 4 diferent species in one tote.
1 B discoids
2 B cranniffer
3 b giganteus
4 hissers.
it seems that the nimphs of each species hang out with their own species, especially the hissers all 30 or 40 of the 1 in nimphs al hang out in a group, they must be able to recignise each other. any body els have thishappen?

yup

My hissers do the same thing. All the nymphs kinda group together and the adults form another group.

My guess is that yes, they can recognize their "siblings." They do communicate with pheromones don't they?

Don't think so.

I hear that roaches depend of physical contact of each other to grow and survive and if the adults are on one side the younger roach won't have room so they all go to another side. As my roaches get bigger and more assertive they tend to go and bug the adults.

they stay in groups of their own species, there is only about 40 hissers but hundreds of giganteus, discoid and deaths heads and they all seem to group by species

I don't know what it is, at first I thought it might have something to do with size only. I have noticed same size nymphs hanging out together under pieces of bark, not exclusively but it's been noticeable to me.
