Most teiids forage quite actively within their ideal temperature range, quickly skirting between cover objects.

Primarily known from lab studies of parthenogenetic Aspidoscelis neomexicanus, simulated mating behavior can increase fertility.

The claim of pseudocopulation was initially met with hesitation by some researchers,[4] and the behavior has not been observed in all parthenogenetic varieties.

Teiids are known to have briefly occurred in Europe during the Late Eocene based on fragmentary fossil material non-diagnostic to the genus level found in the Quercy Phosphorites Formation of France dating to the MP 17 zone.

In some technical literature, the Teiidae are referred to as macroteiids (in opposition to the microteiids, which are members of a sister family Gymnopthalmidae).
