In reply to bishopowl:
Love the idea, came across your post because i was looking for an entomancy mod. Why not use glass containers and bottle the insects, that way you don't have to create another item just for catching them and medieval/fantasy modpack devs wanting to stay away from plastic and modern/sci-fi mods will be more likely to use them.
Rather than just gathering their husks for potions and such why not have certain insects that you can use to attack enemies and retrieve under the idea of them being controlled with magic or something. The idea of tossing a glass bottle of fire ants at someone in modded pvp then gathering them back in a glass bottle afterwards is a bit appealing. If you wanna message me my discord is ShadyTundra#5505 btw.
