Heyetle

Heyetle is a fictional genus of small nocturnal insects described in speculative biology and worldbuilding. It appears in fictional ecosystems to illustrate bioluminescent signaling and ecological interactions, commonly set in the cloud forests of the imagined continent Veridia.

Morphology: adults measure 6–8 mm; wings are translucent with iridescent veins. Photogenic organs along the thorax and abdomen emit blue-green light, primarily at dusk. Males typically have longer antennae and more conspicuous wing patterns than females.

Ecology and behavior: Heyetle species are nocturnal and form loose dusk aggregations. Adults feed on nectar and small arthropods; larvae feed on lichens on bark. Bioluminescence is used in mating and species recognition; predators include bats and insectivorous birds.

Life cycle: females lay eggs on bark or moss. Larvae develop over weeks to months, then pupate. Adults emerge over a brief period and live two to three weeks.

Distribution and habitat: described as endemic to humid cloud forests at 1,000–2,000 meters in Veridia, favoring mossy trunks and epiphytes. Seasonal luminescence patterns are tied to moisture and temperature.

Etymology and cultural notes: the name Heyetle is drawn from a fictional word meaning light. It is cited in worldbuilding guides as an example of bioluminescent signaling and ecological specialization.

Legacy: as a fictional construct, Heyetle has no real-world taxonomic standing but is used to discuss signaling, predation, and habitat use in imagined ecosystems.
