If you have epilepsy and see one run

Approach Glowbug with your Glow puppy. Harvest the charge for the Glow puppy like you would a Water/oil jug bug.

Same behavior and concept of the Jugbug. You walk up to it with a battery in hand and take the charge currently on the bug (0-500 charge storage) and take the charge from it.

They get all spazzy if you kill something near them, or if you snap near them with a Dino. They otherwise move very slowly. Be careful not to spazz them out, especially if you're really low on charge and need them to refill your battery/pet.

Bola and kill to get chitin and meat
