A scavenger species with a veracious appetite for all things edible or nearly edible. Evoreptids are considered pests, based on their tendency to target trash sites but they have also been known to destroy gardens, and trees. They are especially hazardous for bird enthusiasts since they damage feeders and nests and will eat most kinds of bird if they can be caught. Pet owners should also be cautious since Evoreptids have been known to eat animals smaller then them.

Evoreptids are a mammal-like reptile, they are endothermic but thin skinned and lose heat easily, the body's ability to produce heat is directly affected by their calorie intake. It is common to see Evoreptids sunning or seeking out heat sources for these reasons, not because they are ectothermic like other reptiles.

Evoreptids are highly social with their own kind and while they may not always share food, they rarely do serious harm to one another. This could be due to their skittish behavior when it comes to even minimal threats. Many times children walking to school or waiting for the bus have had an Evoreptid snatch their bagged lunch or other treats if the food is unattended. Some parents have expressed concern over this, fearing for their children but experts don't feel school children are in any real danger since Evoreptids don't hunt prey that may fight back, Evoreptids are also easily startled with sudden loud noises and a child's screams would send them running for cover. Their skittish nature makes them especially weary of aggressive body language and behavior so the simple act of throwing a rock or stick will usually end the unwanted encounter.
Some Evoreptids hunt, and some are specialized hunters, but the vast majority are opportunistic scavengers that clean up discarded food and road kill.

These creatures are classed as a non-threatening pest species.
