They can't be tame, but they are a great source of Chitin and/or Cementing Paste (if you have a frog)

Great for chitin if in a group. Have a frog kill them then harvest with sweep attack to get cementing paste. Good for beginners do.

Can’t be tamed, and they are really annoying. Drops chitin, but did these things have to be made?

It sometimes drops meganeura husks.
