 Chauliodes rastricornis (Spring Fishfly) ♀. | Chauliodes rastricornis is a fishfly and can be easily distinguished from dobsonflies by the presence of antennae and jaws (mandibles). This is a large, striking insect. Adult fishflies seemingly do not feed and can be found close to slow moving bodies of water. Females have nearly linear antennae (see photo) whereas males have thick, comb-like ones.
