a little advice om sperm webs.
Usually when a male is done making a sperm web he destroys it, so it might not be as easy as spotting a hammock against the the glass.
I have had males that I never witnessed a sperm web or any evidence of it and they produced slings, males are really sneaky :blink:
I have been fortunate to catch multiple males in the act of producing sperm webs :woohoo: I am amazed every time.
My experience with albopilosum males is that they make sperm webs like crazy, especially when they're not to old.
They will make a sperm web after each mating, maybe even two or three

At least my male did :laugh:
