Bombus insularis
Indiscriminate Cuckoo Bumble Bee
Bombus insularis is a cuckoo bumble bee in the subgenus Psithyrus, native to northern and western North America. As a social parasite, it invades nests of host bumble bee species, usurps the resident queen, and exploits host workers to rear its own offspring. The species is known for its broad host range, attacking multiple bumble bee species across diverse habitats including tundra, taiga, and mountain ranges.
Choristoneura parallela
parallel-banded leafroller moth
Choristoneura parallela, commonly known as the parallel-banded leafroller moth, is a tortricid moth distributed across eastern and central North America. Adults are active from March through October, with a wingspan of 21–23 mm. The larvae feed on a diverse range of host plants including goldenrod, blueberry, rose, citrus, and various other woody and herbaceous species.
Dichomeris setosella
Dichomeris setosella is a gelechiid moth described by James Brackenridge Clemens in 1860. It occurs across eastern and central North America, from Manitoba and New York south to Florida and west to Texas and Oklahoma. The species is recognized by distinctive forewing markings including a pale ochreous triangular patch at the costal base and dark brown patterning. Adults are active from March through November. Larvae feed on a diverse range of host plants including Asteraceae species and conifers.
Endothenia hebesana
Verbena Bud Moth
Endothenia hebesana is a small tortricid moth commonly known as the verbena bud moth. The species has a broad North American distribution spanning from the Atlantic coast to the Pacific. Larvae develop inside the flower stalks and seed heads of numerous plant species, particularly in the genera Verbena and Penstemon. Fourth and fifth instars overwinter within host plant stems, with pupation occurring in late spring.
Eriotremex formosanus
Asian Horntail
Eriotremex formosanus is an Asian horntail wasp (family Siricidae) native to Asia that has been introduced and established in the southeastern United States. Unlike most siricid wasps, which specialize on conifers, this species exhibits unusually broad host associations, utilizing both coniferous and hardwood tree species. Females possess a long ovipositor for drilling into wood and deposit eggs along with fungal symbionts (Amylostereum areolatum) that larvae feed upon during development. The species targets stressed, dying, or recently dead trees rather than healthy timber.
Listroderes costirostris
vegetable weevil
Listroderes costirostris, commonly known as the vegetable weevil, is a weevil species in the family Curculionidae. It is native to southern South America but has been introduced to multiple continents. The species is recognized as a significant agricultural pest with a broad host range that includes vegetables and weeds. It has established populations in North America, Europe, Asia, Africa, and Oceania.
