Adult flies have no functional mouthparts and live only 1-2 weeks — like other Oestridae, the entire purpose of adult life is the elaborate egg-laying cycle.

Face flies are the primary vector of Moraxella bovis — the bacterium that causes cattle pinkeye, a major economically significant dairy and beef cattle disease.

Adult face flies aggregate on cattle faces (eyes, nostrils, mouth) and feed on tears, mucus, and saliva — using sponge-like labellar mouthparts.

Native to Eurasia, accidentally introduced to Nova Scotia in 1952 — has since spread across the entire eastern, central, and northern US and southern Canada.

Like cluster flies, face flies overwinter in rural attics, wall voids, and unused upper rooms by the THOUSANDS — major autumn nuisance pest of farmhouses.

Face flies are virtually indistinguishable from the closely related house fly except by careful examination of male reproductive structures — same Musca genus.

Flame skimmer males are entirely BRILLIANT FLAME-RED across the body, head, and wing veins, with orange-tinted wings — appearance of a small flying ember.

She is a sit-and-wait perching predator — defends small territories from prominent perches and sallies out to capture passing flying insects.

She is one of the most ecologically important mosquito predators in arid western US pond habitats — desert oases, reservoir margins, agricultural ponds.

Naiads tolerate warm, low-oxygen, alkaline desert oasis pond conditions where many other dragonfly species cannot persist.

Among the most-photographed dragonflies in the American Southwest because of the dramatic coloration and predictable perching behavior.

Pipevine swallowtail caterpillars sequester ARISTOLOCHIC ACIDS from pipevine host plants — potent renal-toxic alkaloids that make adults severely bird-aversive.

She is the MODEL species of one of the most extensive mimicry complexes in North American butterflies — at least 5 other species converge on her wing pattern.

Mimics include: eastern tiger swallowtail dark form, spicebush swallowtail, black swallowtail, red-spotted purple, female Diana fritillary — both Batesian (palatable mimics) and Müllerian (toxic mimics) species.

Adults have brilliant iridescent blue scaling on the upperside hindwings — males much more intensely blue than females. Among the most spectacular dark-iridescent butterflies in eastern North America.

Birds that try a pipevine swallowtail once vigorously avoid the species and any visually-similar species for the rest of their lives — the basis of the entire mimicry complex.

The viceroy was universally taught as the classic example of Batesian mimicry from the 1860s through the 1980s — assumed to be palatable, gaining protection by mimicking the toxic monarch.

Ritland and Brower's 1991 experiments overturned the textbook consensus — birds REJECT viceroy abdomens at high rates, proving the species is itself chemically defended.

The viceroy/monarch relationship is MÜLLERIAN mimicry (both species toxic, both reinforce warning) — NOT Batesian (palatable mimic of toxic model) as previously taught.

Viceroy caterpillars feed on willows and sequester salicylic acid (precursor of aspirin) and other distasteful phenolics — the source of the species' chemical defense.

Mainstream biology textbooks took roughly 20 years to fully revise the 'Batesian viceroy' interpretation — one of the most-cited examples of slow scientific consensus revision.

The zebra longwing is the official state butterfly of Florida — designated by the state legislature in 1996.

Like other Heliconius, she eats POLLEN — gathers pollen on the proboscis, regurgitates saliva to liquefy it, drinks the amino-acid-rich liquid. Lives 6-9 months as a result.

Large groups (5-60 butterflies) roost communally every night — returning to the same site over weeks or months. Predator-protection aggregations and social hubs.

Males patrol female pupae and copulate with the females WHILE they are emerging from the pupa — sometimes before the female has fully extracted. Highly debated behavior.

She sequesters cyanogenic compounds from larval Passiflora host plants — adults are bird-aversive and the bold zebra striping is honest aposematic warning.

Zebra swallowtail is the official state butterfly of Tennessee — designated by the state legislature in 1995.

Hindwing tails are ~3 cm long — the longest tail extensions of any North American swallowtail butterfly.

Caterpillars feed EXCLUSIVELY on pawpaw (Asimina triloba) — the largest native fruit-bearing tree in temperate North America.

She is a useful indicator species for native pawpaw forest health — present where pawpaw groves are healthy, absent where pawpaw has been lost to deer browsing pressure.
