Roach sweat?

I know roaches dont really sweat, but sometimes I notice small droplets of brown fluid accumulating on my roaches wings, when I rub it off it stains my hands. What are these secretions?

 
I would get a picture but the droplets are so small they would be blurry.

I was just reading how pest roaches secrete an oily liquid that if comes in contact with food may leave a bad smell, could my roaches just have an excess amount of that oil being they are captive roaches, where wild roaches would be rubbing it off more often.

There are 7 roaches living in a 20 gallon. They have wood chips for substrate, and a shallow water dish to drink from. They get fresh fruits/veggies/cat kibble each day, nothing rots inside. It's fairly dry.

I dont know what is causing this but they are over 2 years old, it cant be due to illness or they would have died long ago. 2 years is very long for Fusca to live.

I'm thinking they have excess oils due to there diet, they get protein (cat kibble) everyday with there fruits and veggies.

 
I had experianced this to, at my blaberus giganteus colony, especiali among males.

Maybe is some kind of pheromone. If you grab this sp. of roaches in your hand and small it, it will stink...maybe is this what we saw...defence odor in the form of drops.

 
You may be onto something, but...

#1 they are all female

#2 they werent being handled by me, they were just in there cage doing nothing.

 
Hmm.

I've seen this on E. posticus.

Maybe it's some fluid leaking from the wings after another roach nibbled on them.

 
I've had hissers and lats spit on me. Dubias spit too. I'm pretty sure it came out of their mouth. Haven't seen it on their wings though. That's interesting.
