During zoea II (2-day-old larvae), the peduncle has 2 segments, with some plumose setae

Puthoff found that softer, more deformable setae
could explain the gecko's improved attachment at high humidity.

A wide variety of antennal and antennular setae

Nymphs of Cultus can be separated from other North American Perlodinae genera by the combination of the following characters; lacinia bidentate with few marginal setae
, pronotal setae
restricted to 2-3 at corners, and mesosternal Yarms well developed, reaching posterior corners of furcal pits, transverse suture connecting furcal pits absent (Stewart and Stark, 2002).
