Distremocephalus
glowworm beetles
Distremocephalus is a genus of glowworm beetles in the family Phengodidae, established by Wittmer in 1976. The genus comprises approximately 11 described species distributed across North America, primarily in the southwestern United States and Mexico. Members are bioluminescent beetles commonly known as glowworms, with most species described by Zaragoza in 1986.
Microphotus angustus
California Pink Glowworm
Microphotus angustus is a firefly species in the beetle family Lampyridae, commonly known as the California Pink Glowworm. It is found in North America, with distribution records spanning Middle America and North America. The species was described by LeConte in 1874. As a member of Lampyridae, it possesses bioluminescent capabilities, though specific details of its light production and mating signals remain poorly documented in available sources.
Phengodes laticollis
glowworm beetle
Phengodes laticollis is a glowworm beetle in the family Phengodidae, notable for pronounced sexual dimorphism and bioluminescence across all life stages. Females are larviform, larger than males, and produce yellow or green light from organs on trunk segments. Males are smaller, winged, and possess large curved mandibles. The species has been documented circumventing millipede chemical defenses through specialized predatory behavior.
Phengodes mexicana
glowworm beetle
Phengodes mexicana is a species of glowworm beetle in the family Phengodidae. The species was described by Wittmer in 1976. It occurs in Central America and North America. Members of the genus Phengodes are notable for their bioluminescent larvae and adult females, which are wingless and resemble larvae in appearance.

Phengodidae is a family of bioluminescent beetles commonly known as glowworm beetles. The family contains over 250 described species distributed throughout the New World from southern Canada to Chile, with additional diversity in Western Asia through the subfamily Cydistinae. Females and larvae possess bioluminescent organs that emit yellow, green, or red light; the Brazilian railroad worm Phrixothrix hirtus is the only terrestrial organism known to produce true red light. Females are larviform and typically much larger than males, which are winged, short-lived, and often attracted to lights. The family was formerly considered to include the Old World Rhagophthalmidae, now recognized as a separate family.
Photinus ignitus
Ignited Firefly
Photinus ignitus is a North American firefly species distinguished by its bioluminescent courtship displays. Males produce characteristic flash patterns to attract females, who respond from perches in vegetation. Research has documented seasonal plasticity in female mate choice behavior, with females becoming less selective as the breeding season progresses. Like other Photinus species, it produces defensive compounds called lucibufagins that protect against predators.

Florida Single Snappy
Photuris congener is a firefly species in the predatory genus Photuris, first described by LeConte in 1852. Like other Photuris species, females are known to practice aggressive mimicry, luring males of other firefly genera through flash pattern imitation. The species is commonly known as the 'Florida Single Snappy' and occurs in North America. As with congeners, it produces bioluminescence through a luciferin-luciferase reaction in specialized abdominal photocytes.
