I would then very carefully dip my spider into the resin and allow to dry. Thats going to be the tricky part as you will need to set her on something that allows her to keep her shape in addition to not destroying her when you go to get her after she cures. My suggestion would be to set her on a silicone mold of some sort as you can just bend the mold to get her loose. If you dont have one, then my next suggestion would be a piece of wax paper (resin peels away from wax paper). Shes going to pool resin, so be prepared to trim off any extra after she cures.
I have recently taken up making paper weights by encasing dead scorpions in resin with good results so far. Alchohol works great to clean them and it only takes a few hours for them to dry. I fill the mold halfway then set them in (upside down since the mold is upside down). Then I let it set up for about an hour and a half before pouring the rest of the resin in. The reason for this is because the light weight arachnid will float to the top while the resin is setting. This way the specimen winds up floating in the center when everything drys completely
Encased insects are beautiful but please think about the time you are freezing them for before placing them in resin. A spider who has spent 1 hour in the freezer will only be in hibernation. The best practise, to be sure this is done humanely, is to.leave them in the freezer over night and then submerge in alcohol. Only this way can you be sure they are dead. Even freezing over night only assures hibernation, not death, so the alcohol step is important. Good luck and I would love to see some of the finished results!
In order to be prepared for unexpected births, you should provide your scorpions with a substrate that allows for the creation of deep burrows.Tunnel and burrow walls will remain intact in a slightly moist mix of peat moss, sand, top soil and Eco Earth.If your female gives birth in a tank that is not set-up as described, try adding a commercial cave stocked with moist sphagnum moss.If the substrate is deep enough, bury the cave so that the opening is flush with the surface.
It is a bad idea to keep scorpions unless you can identify the species and are sure they are not dangerous. The venoms of several species have caused human deaths; even those considered not deadly can cause serious illness or death if a person happens to be sensitive or allergic to their venom. We know nothing about the venoms of others; many in Bangladesh have not been studied.
Sounds like you are doing fine; after the first molt, there is usually a great deal of variation as to when each will molt again; no general rules, other than that growing youngsters molt more frequently than sub-adults. You can expect to see size differences as time goes on also; this is typical, no need for concern. Groups can be reared together, but this may make it harder to keep track of feeding etc. Enjoy and pl keep me posted, Frank
