They become agressive around dead bodies

People say when ur a low level stay away but if u have a spear then they are a GOOD source of xp and plus if u get low just go prone and heal trust me do this

those mf can eat a whole bronto in less than 5 seconds, so if you kill anything big and want to harvest its body, make sure to kill them instantly because they spawned near dead bodies or say bye to the body.

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

When I saw them for the first time I was like well they are probably not dangerous they are just giant firefly and then they attack me and I won but srsly they are so dangerous so now I am keeping them away from me

To fight them off, look up at a 45° angle (not straight up, not straight forward, but halfway between both) and keep attacking.
They will start dropping like flies.

I think you should NOT fight near them If you a beginner 😀🤪

They only attack you if you attack them or something nearby.

Make sure they're not around when harvesting dead dinos. They do lots of damage and can kill you before you even know what killed you. They only target you If you're harvesting a dead body that they are after.

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!
