Cyladini
Cyladini is a tribe of weevils in the family Brentidae, subfamily Apioninae. The tribe includes economically significant pests of sweet potato, particularly the sweetpotato weevil (Cylas formicarius), which causes substantial damage to storage roots in tropical and subtropical production regions. Members of this tribe are characterized by their association with Convolvulaceae host plants and their status as specialized root-feeding pests.

Dielis tolteca
Toltec scoliid wasp
Dielis tolteca is a species of scoliid wasp native to western North America and Mesoamerica. The species is known to parasitize scarab beetle grubs, with females hunting underground hosts to provision their offspring. Adults have been observed feeding on flowering plants, particularly mustards (Brassicaceae) and goldenrods (Solidago). The species has been documented in McInnis Canyons National Conservation Area in western Colorado, where it is active as a spring-emerging species.

Signal Crayfish
The signal crayfish is a large North American freshwater crayfish introduced to Europe in the 1960s to replace declining native fisheries. It has become one of the most ecologically impactful invasive decapods in Europe, outcompeting native crayfish and serving as a carrier of crayfish plague (Aphanomyces astaci). The species establishes self-sustaining populations rapidly, with six age cohorts documented within a few years of introduction. It shows sex- and size-specific coloration patterns, with males displaying more saturated and brighter ventral claw surfaces than females, suggesting a role in intraspecific communication.
