8 months or so on average. And nope, all life stages can be housed together, so long as they have PLENTY of protein (dog food or something similar) available at all times and a good amount of surface area. :)
Prolific but slow growing, so could probably only be used as occasional feeders... But my tarantula loves them, and she's a super picky eater!
BIG lol, their bodies alone get almost two inches long, and their legs are so long... Honestly this IG post of mine shows their size off best I think:
Believe me, if they could infest houses, my mom woulda killed me by now... :ROFLMAO: They can't survive more than a few days outside their enclosures with how small they are, they'd dry up super fast.
For tiny, non climbing, non burrowing feeders, I highly recommend Compsodes schwarzi. They are very prolific, active little things that are easy to breed and would work great for smaller predators, (adults are around 7 mms long). They just need moisture, lots of hides, warmth for the fastest...
You have no idea how bad I want those LOL! There's also a couple south american species where the larvae glow very brightly from their heads, stick their heads out of the ground/termite mounds they live in, and attract prey items to them with their luminescence... :D
