Inhabit gravel and rubble riffles of headwaters, creeks and small rivers. Also occur in springs and their effluents (Ref 5723, 10294). Young feed on aquatic insect immatures of many kinds, including caddisflies, mayflies, and midge larvae; adults on stonefly nymphs and maturing stages of other insects (Ref. 10294).

Estimates based on models
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00300 - 0.01523), b=3.17 (2.98 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 3.4 ±0.5 se; based on size and trophs of closest relatives
Resiliência (Ref.
120179): médio(a), tempo mínimo de duplicação da população 1,4 - 4,4 anos (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
