Brachylampis
Brachylampis is a genus of fireflies (family Lampyridae) described by Van Dyke in 1939. The genus contains at least two species: B. blaisdelli and B. sanguinicollis, both described in the same year. It belongs to the subfamily Ototretinae, a group of fireflies characterized by reduced or absent light-producing organs in adults. Information on biology and ecology remains sparse due to limited study and few observations.

Cenophengus
glowworm beetles
Cenophengus is a genus of glowworm beetles (family Phengodidae) comprising 30 valid species distributed across the Nearctic and Neotropical regions from the southwestern United States through Central America. Males are the only known life stage; females and immature stages remain undiscovered for all species. The genus was revised taxonomically in 2021, with new species described and geographic records expanded to include Belize and Honduras for the first time.

Cenophengus pallidus
Pale South Texas Glowworm
Cenophengus pallidus is a species of glowworm beetle in the family Phengodidae. It was described by Schaeffer in 1904 and is found in North America. The species is commonly known as the Pale South Texas Glowworm. Like other phengodid beetles, adults are bioluminescent, with females and larvae typically exhibiting the characteristic glowworm luminescence more prominently than males.

Disholcaspis prehensa
clasping twig gall wasp
Disholcaspis prehensa is a gall-inducing cynipid wasp native to California that induces distinctive galls on scrub oak and leather oak. The species exhibits heterogony, alternating between sexual and asexual generations that produce two morphologically different gall types. The asexual generation forms conspicuous mushroom-shaped twig galls with clasping bases, while the sexual generation produces small, hidden bud galls.

Elateridae
Click Beetles, elaters, snapping beetles, spring beetles, skipjacks
Elateridae, commonly known as click beetles, is a cosmopolitan family of beetles characterized by a unique clicking mechanism used for defense and righting. The family contains approximately 10,000 species worldwide. Members possess a prosternal spine and mesosternal notch that, when snapped together, produce an audible click capable of launching the beetle into the air. Some species exhibit bioluminescence, with about 200 luminescent species known primarily from Latin America and Oceania, and one recently discovered in Asia. Larvae, known as wireworms, are often soil-dwelling and can be significant agricultural pests.

Elateroidea
Click, Firefly, and Soldier Beetles
Elateroidea is a large superfamily of beetles comprising approximately 25,000 species across multiple families. It includes the familiar click beetles (Elateridae), fireflies and glow-worms (Lampyridae and related families), and soldier beetles (Cantharidae). The superfamily exhibits remarkable morphological diversity, ranging from hard-bodied forms with five abdominal ventrites to soft-bodied forms with 7-8 ventrites connected by membranes. Bioluminescence has evolved independently in multiple lineages, particularly within the lampyroid clade and certain Elateridae. A distinctive clicking mechanism using a prothoracic peg and mesothoracic cavity is present in several sclerotized families, enabling the characteristic jumping behavior of click beetles.

Ellychnia greeni
Ellychnia greeni is a firefly species originally described in the genus Ellychnia but currently recognized as a synonym of Photinus greeni. The species was described by Fender in 1962 and is known from North America. Like other members of the family Lampyridae, it is a beetle with bioluminescent capabilities, though specific details about its biology remain limited in available sources.

Keroplatidae
Predatory Fungus Gnats, Fungus Gnats
Keroplatidae is a family of small, delicate flies in the order Diptera, commonly known as predatory fungus gnats. The family comprises approximately 950 described species, though true diversity is estimated to be substantially higher. Members are predominantly forest-dwelling insects associated with damp microhabitats where fungi occur. The family is notable for containing three genera—Arachnocampa, Orfelia, and Keroplatus—with bioluminescent larvae, commonly called "glowworms." Larval ecology varies: some feed on fungi, others are predatory, and many combine both strategies. The fossil record extends to the Cretaceous period.

Keroplatus
Keroplatus is a genus of predatory fungus gnats in the family Keroplatidae. Larvae of several species exhibit weak blue bioluminescence, making this genus one of the few terrestrial insect groups capable of producing light. The genus is poorly studied compared to other bioluminescent insects, with limited ecological and behavioral data available. Riboflavin has been identified as a possible component of the bioluminescent system in at least one species.

Lampyrinae
typical fireflies
Lampyrinae is the largest subfamily of fireflies (Lampyridae), comprising over half of the family's genera. Historically used as a 'wastebin taxon' for fireflies with unresolved relationships, recent molecular phylogenetics have clarified its boundaries as a monophyletic group. The subfamily exhibits exceptional diversity in bioluminescent communication, including both flashing and continuous-glow species distributed across the Holarctic and tropical regions. Ancestral Lampyrinae likely possessed primitive or absent light signals, with several modern lineages independently reverting to pheromone-based communication.

Lampyrini
glowing fireflies, continuous-light fireflies
Lampyrini is a tribe of fireflies (subfamily Lampyrinae) containing the typical 'glowing' or 'continuous-light' fireflies of the Holarctic region. The tribe includes the type genus Lampyris and formerly recognized Pleotomini, which molecular evidence indicates is a specialized offshoot nested within Lampyrini.

Pyrophorini
Headlight Beetles
Pyrophorini is a New World tribe of click beetles (Elateridae: Agrypninae) characterized by bioluminescence in both larvae and adults. The tribe comprises approximately 20 genera including Pyrophorus, Ignelater, and Pyrearinus. Members are known for producing light through specialized organs, with larvae associated with phenomena such as 'luminescent termite mounds' and 'luminous canga caves' in South America. The tribe is believed to be monophyletic and is closely related to Anaissini, which contains some but not all bioluminescent species.

Stictocephala stimulea
Stictocephala stimulea is a treehopper species in the family Membracidae, first described by Van Duzee in 1914. Treehoppers in this genus are characterized by their enlarged, often ornate pronotum that extends over the body like a helmet or thorn. The specific epithet 'stimulea' suggests possible resemblance to or association with stinging organisms, though this refers to appearance rather than actual sting. Like other membracids, this species likely feeds on plant phloem sap using piercing-sucking mouthparts.
