Pteronymia cotytto

Cotytto Clearwing

(Guérin-Méneville, [1844])

Detailed Texts Multi-lang
A small, delicate brush-footed butterfly famous for its largely transparent wings framed by thin, reddish-brown or dark borders. The absence of colored scales on most of the wing surface creates a striking window-like effect.

Habitat SummaryOverview of the specific ecosystems and environments where this species is found in Costa Rica. Multi-lang

Inhabits tropical rainforests, cloud forests, and secondary growth areas from Central America down into northern South America. They thrive in humid environments and are typically found flying low in the shaded understory.

BehaviourDaily activity patterns, movement, territory use, foraging style, and seasonal behavioral changes. Multi-lang

Diurnal flyers that spend most of their time hovering slowly inside the deep shade of the forest floor, avoiding bright open spaces. They participate in mimicry rings with other clearwing species to enhance predator deterrence.

Social ActivitySocial structure: whether the species is solitary, paired, or colonial; hierarchy and communication. Multi-lang

Generally solitary while foraging, but males frequently aggregate in shaded hillside areas or 'leks' to release pheromones collectively and attract females.

Feeding GuildWhat the species eats, how it forages or hunts, and its role as a consumer in the food web. Multi-lang

Nectarivorous adult, herbivorous larva (folivore).

Trophic Chain DetailsSpecific interactions in local food webs: prey species, predators, competitors, and scavengers. Multi-lang

Caterpillars are specialized herbivores feeding on Solanaceae (such as Solanum or Cestrum). Adults feed on nectar and moisture. Adults are avoided by most insectivorous birds due to toxicity, but can fall prey to spiders and dragonflies.

Reproductive BehaviourMating strategies, courtship displays, nesting or spawning behavior, and parental care. Multi-lang

Males establish small territories in leks under the canopy. After mating, females locate appropriate larval host plants in the understory to lay single, tiny eggs on the undersides of leaves.

Sexual DimorphismPhysical differences in size, coloration, or morphology between males and females of this species.

Males Multi-lang

Males possess specialized androconial scent patches (hair pencils) along the costal margin of the hindwings, used to disperse pheromones during courtship.

Females Multi-lang

Females lack androconial hair patches on the hindwings and generally have a slightly broader, rounder abdomen adapted for egg production.

Evolutionary AdaptationsInherited traits and behaviors that improve the species' survival and reproduction in its specific environment. Multi-lang

The transparent membrane of their wings lacks scales, allowing background patterns and light to pass through completely, rendering them nearly invisible to predators while flying in shaded forests.
As caterpillars, they feed on toxic plants primarily in the Solanaceae family, sequestering chemical toxins that remain in their bodies as adults, making them unpalatable to birds.

Main ThreatsDocumented pressures reducing the population: habitat loss, hunting, disease, climate change, and invasive species. Multi-lang

Habitat fragmentation and deforestation caused by agricultural expansion and logging, which destroys the understory and larval host plants.
Climate change, which alters the humidity and temperature balance required by sensitive tropical clearwing butterfly populations.

Interesting FactsSurprising or notable facts that highlight what makes this species unique or ecologically important. Multi-lang

Adult males often feed on the nectar of Asteraceae plants to extract pyrrolizidine alkaloids. These chemicals are essential for the production of courtship pheromones used to attract females.
