PhylumRank below Kingdom. Groups organisms sharing a fundamental body plan (e.g., Chordata = vertebrates and some invertebrates).Chordata
ClassRank below Phylum. Subdivides by structural traits (e.g., Mammalia, Aves, Reptilia, Insecta).Mammalia
OrderRank below Class. Groups related families sharing common ancestry (e.g., Carnivora, Primates).Chiroptera
FamilyRank below Order. Groups closely related genera (e.g., Felidae = cats, Canidae = dogs).Emballonuridae
GenusRank just above Species. The first word in the two-part binomial scientific name.Peropteryx
Taxonomic AuthorityThe scientist who first formally described and published this species, followed by the year of publication.(Wagner, 1843)

Habitat SummaryOverview of the specific ecosystems and environments where this species is found in Costa Rica. Multi-lang
Inhabits tropical lowland forests, often roosting in caves, rock crevices, or hollow trees.BehaviourDaily activity patterns, movement, territory use, foraging style, and seasonal behavioral changes. Multi-lang
Nocturnal, insectivorous, and relatively shy when roosting.Social ActivitySocial structure: whether the species is solitary, paired, or colonial; hierarchy and communication. Multi-lang
Form small harem groups or solitary individuals.Feeding GuildWhat the species eats, how it forages or hunts, and its role as a consumer in the food web. Multi-lang
Aerial insectivore.Trophic Chain DetailsSpecific interactions in local food webs: prey species, predators, competitors, and scavengers. Multi-lang
Feeds primarily on small flying insects captured on the wing.Reproductive BehaviourMating strategies, courtship displays, nesting or spawning behavior, and parental care. Multi-lang

Females1 - 3 Years
Sexual DimorphismPhysical differences in size, coloration, or morphology between males and females of this species.
Males Multi-lang
Males are slightly larger and possess visible glandular sacs on the wing membranes.
Females Multi-lang
Females are smaller and lack the developed wing sacs.
Evolutionary AdaptationsInherited traits and behaviors that improve the species' survival and reproduction in its specific environment. Multi-lang
Glandular wing sacs in males produce scents used in social signaling and attracting females.
Main ThreatsDocumented pressures reducing the population: habitat loss, hunting, disease, climate change, and invasive species. Multi-lang
Disturbance of roosting sites and loss of forested foraging areas.
Interesting FactsSurprising or notable facts that highlight what makes this species unique or ecologically important. Multi-lang
They are known for their distinct roosting posture, often hanging individually rather than in large, dense clusters.
