Advertisement Hello! I'm new here. But, I've been enthused with jumping spiders for a long time. Here in Pennsylvania, bold jumping spiders are very common. I'm raising 5 of them, all juveniles, and all are slightly larger than a common house fly. The thing is, I'm hoping to get a male, as I've only ever had luck catching adult females, so I captured juveniles hoping for different results. But I'm impatient. I wanna know or have a general idea what sexes they are now. Also based on them all being similarly sized to a common house fly, what instar are they likely in? About the sexes, what could I look for in juveniles to distinguish them? Is there any difference between a juvenile male and female at all? I will upload photos of 4 of the spiders upon request, as one of them has setup a molting sac and has been in it for a few days.
