[9][10] Whether they do it in response to temperature (thermoregulation) is less clear, with studies both supporting it[11] and contradicting it. This species has been chosen as a model reptile for genomics by the National Human Genome Research Institute genome sequencing program. [2], This species is native to North America, where it is found mainly in the subtropical southeastern parts of the continent. [17] Adult flies will deposit eggs on live anoles, and the fly larvae develop inside the lizard until they emerge from a wound and pupate into adult flies in sediment. They spend almost a fourth of their time up in trees or bushes.
