• Habronattus brunneus

  Habronattus brunneus is a species of jumping spider in the family Salticidae, first described by George and Elizabeth Peckham in 1901. It occurs in the United States and Caribbean, including the Bahamas, Dominican Republic, Haiti, Hispaniola, and the Virgin Islands. Males discriminate between substrate-borne cues from females based on age and mating status, spending more time exploring cues from mature, non-mated females. Populations exhibit differing prey colour biases, with some showing strong avoidance of red prey and others showing no colour bias.

• Hesperophylax

  Hesperophylax is a genus of northern caddisflies (Trichoptera: Limnephilidae) comprising seven described species distributed across western North America. The genus is characterized by morphological plasticity and broad habitat tolerance compared to other Trichoptera. Larvae construct portable protective cases and exhibit chemically-mediated antipredator behaviors. All species appear to be univoltine with extended adult flight periods.
