Austin sits at the far southwestern corner of the range of the Eastern Firefly (Photinus pyralis), the species that gives eastern landscapes the characteristic dusk light show in early summer.

The Daily Species: Lesser Siren (Siren intermedia)
The Lesser Siren (Siren intermedia) is a slender-bodied aquatic amphibian that spends its days burrowed in silt and debris at the bottom of slow waters.

During drought, they can secrete a protective mucus that cocoons t...

This species can be highly arboreal and is adaptable to a wide range of habitats. Because of this versatility, they feed on a variety of prey (small mammals, birds, reptiles) that they kill by constriction. Ratsnakes are so...

The photographs of the hatching eggs (above) and adult butterfly (below) are public domain images created at UT ...
