Anax walsinghami
giant darner, giant green darner
Anax walsinghami is the largest dragonfly species in North America, with a wingspan reaching up to 120 mm and body length of 89–117 mm. Commonly known as the giant darner or giant green darner, this species belongs to the family Aeshnidae and is distributed across Central America and North America. Despite its impressive size, it is exceeded by the closely related giant Hawaiian darner (A. strenuus). The IUCN lists the species as Least Concern with a stable population.

Bombus griseocollis
brown-belted bumblebee, brown-belted bumble bee
Bombus griseocollis is a widespread North American bumblebee species commonly known as the brown-belted bumblebee. It is notable for its flexible habitat use, occurring in both natural and heavily urbanized environments including densely populated cities. The species maintains stable populations across much of its range, in contrast to many declining North American bumblebees. It exhibits primitively eusocial colony organization with temporal division of labor among workers.

Cordulegaster erronea
tiger spiketail
Cordulegaster erronea, the tiger spiketail, is a large, uncommon dragonfly in the family Cordulegastridae. It is a habitat specialist requiring small, pristine, spring-fed forest streams with muck bottoms and overhanging vegetation. The species has a long larval period estimated at 3-4 years and a brief adult flight period of approximately 2-3 weeks in early summer. Radio-telemetry studies in New Jersey have revealed limited adult movement, with individuals typically remaining within 100-200 meters of natal streams and showing strong site fidelity.

Vespula infernalis
cuckoo yellowjacket, American cuckoo yellowjacket
Vespula infernalis is an obligate social parasite (inquiline) that invades and usurps colonies of other yellowjacket species, primarily Vespula acadica in North America. Unlike most parasitic wasps, it exhibits intensely aggressive behavior during colony takeover, using specialized morphological adaptations including a large, heavily curved stinger to subdue host workers. The species lacks a worker caste and cannot build nests or rear its own young, instead forcing host workers to feed and care for its brood through dominance behaviors including mauling and forced trophallaxis.
