DO NOT EAT ORGANIC POLYMER, THEY WILL NOT COME TO YOU. YOU WILL DIE.

Use a torch. They have very little health but are difficult to target. Using fire lights them up and kills them quickly and safely.
Bonus points if they are attacking at night, as you will have several extra, flying torches for a few seconds!

They will only agro if a corpse is present and you go near them, just like the vulture in ark.

Beat it, then claim yer free chitin.

I just hate them for me these little bugs always come at the wrong time
And i have almost infinite chitin but
They are fine for paste
