After being misidentified as Vermicella ameghini, in 1989 it was suggested to be Belocaulus angustipes, and was decisively confirmed in 2009. Historyīelocaulus angustipes was first collected in Mobile, Alabama in August of 1960 then in New Orleans shortly thereafter. They tend to live underneath living or inanimate objects such as fallen trees, planks and garden pots. Biologyīelocaulus angustipes is typically nocturnal, and avoid sunlight extreme heat, cold or low humidity. Their insatiable appetite makes them a threat to many kinds of grasses and plants. This is our main concern for their prescence in Texas. In Honduras, where it is also invasive, it was reported as an important vector of the nematode parasite Angiostrongylus costaricensis that causes abdominal angiostrongyliasis in humans. Young slugs are not as dark, and their underside is much lighter. Both the breathing pore (pneumostome) and anus are located posteriorly. The velvety/wrinkled mantle covers the entire length of the body. They have two ocular tentacles that are also black. As the common name suggest, this slug is typically jet black with an inconspicuous tan stripe down the underside. This terrestrial slug is from the family Veronicellidae (leatherleaf slugs) andcan grow up to 3.5 inches in length.
