Host-fidelity

• Cedusa inflata

  Cedusa inflata is a derbid planthopper in the family Derbidae. Its larvae develop exclusively in decaying palm tissue, a specialized habitat that directly determines where adults occur. Adults are found on living palms, specifically the same palm species where larval development took place. This tight coupling between larval habitat and adult distribution represents a notable ecological pattern among planthoppers.

• 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.
