The head of A. lugubris is large relative to the body. Reproduction Aneides lugubris breeds in late spring or early summer. The female lays twelve to twenty-four eggs in a moist hollowed area such as a rotten log or tree hollow. It often hides during the day and in dry seasons. The arboreal salamander likes moist places in leaf litter where it can hide during the day and forage food at night.
Some sources label A. lugubris as being a sensitive species as well as being relatively rare.
As with many animals, A. lugubris 's primary threat is habitat fragmentation due to human development. Behler, J. and F. King. National Audubon Society Field Guide to North American Reptiles and Amphibians. Alfred A. Knopf, . Harding, J. 1997.
