Larvae secreting black liquid?

[GeneralZero]

Sometimes I notice that one or two larvae will secrete a black looking liquid out of their mouths or rectum when I inspect them they seem fine...just worries me. Anyone know of what this is or have experienced this?

Is this the same as reflex bleeding? Where they deliberately bleed or something to fend away possible threats or predators? It says that beetles do this at times as well so is it logical to believe larvae would as well?

i dont think thats good... if u handle gently they wont make the liquid as much... i just use spoon to hold the larvae

i noticed the liquid smell really bad so try not to bother them too much...
