What a Tliltocatl albopilosus sling looks like after molting?

Hello! So, my sling has been in their burrow for awhile, so I can't get that great of a look, but when i saw them against the glass today, I noticed that their legs were black now, and now I can properly see their fangs. And so I was just wondering if this is what a Tliltocatl albopilosus sling looks like after molting? They are still small though. And if they did molt, how long should I wait till I try and feed them? I always feed them dead insects, but I just don't know if there's a certain time frame really.
