In striped plateau lizards (Sceloporus virgatus), females during the breeding season develop an orange color on their throat area signaling that they are ready to mate, and it represents a higher quality female (fewer ectoparasites, and larger egg mass). Use them in commercial designs under lifetime, perpetual & worldwide rights.

If they are currently fighting and you dont separate them, then eventually they may fight again and one of the lizards may become badly hurt. "mainEntity": [ This results in fertilized eggs.
