• Euschistus servus

  Brown Stink Bug

  Euschistus servus, commonly known as the brown stink bug, is a native North American pentatomid species distributed across Central America and North America. It is a significant agricultural pest in the southern United States, feeding on a wide range of crops including soybeans, cotton, corn, peanuts, peaches, and pecans. The species is highly mobile, capable of dispersing up to 15.9 km in flight mill studies, and exhibits seasonal movement between crop hosts and non-crop habitats. Two subspecies are recognized: E. s. servus and E. s. euschistoides.

• Pinnixa chaetopterana

  tube pea crab

  Pinnixa chaetopterana is a small, soft-bodied pea crab that lives symbiotically within the tubes of polychaete worms, primarily Chaetopterus variopedatus. It is a facultative commensal, occasionally free-living or associating with alternative hosts such as Amphitrite ornata. The species exhibits strong host fidelity and can distinguish conspecifics from heterospecifics. It ranges from Massachusetts to Uruguay along the western Atlantic, including Brazil and the Gulf of Mexico.
