Eastern firefly
Photinus pyralis
Also known as: common eastern firefly, lightning bug, big dipper firefly
The most-common firefly across the eastern U.S. — the iconic summer-evening flashing yellow light of a Northeastern childhood. Larvae and adults are bioluminescent; the flashing pattern is species-specific and is the species' mating signal. Common across Staten Island in early summer in lawns, meadows, parks, woodland edges. Population declines from light pollution, pesticide use, and habitat loss are documented across the genus.
Scientific
Photinus pyralis is a 0.5–0.75 inch beetle in the family Lampyridae — fireflies are technically beetles, not flies. Adults flash a yellow-green light from abdominal lanterns at species-specific patterns. P. pyralis males flash a single ½-second pulse rising in flight (the “J-stroke” pattern) every ~5 seconds; females flash from the ground in response.
Larvae are also bioluminescent; they’re predatory, feeding on snails, slugs, and earthworms in soil and leaf litter. Adult fireflies of this genus eat little or nothing during their short adult lives.
Firefly populations across many U.S. species have declined significantly. Documented causes: light pollution (which interferes with mating signals), broad-spectrum lawn pesticides (kill both larvae and prey), habitat loss, and climate-altered seasonal timing. Photinus pyralis remains broadly common but local population dynamics vary.
On Staten Island
Common in lawns, meadows, parks, and woodland edges in late June and July. Mass evening displays are visible at the Greenbelt edges, in less-lit residential blocks, and at large parks. Light pollution from the borough’s developed areas reduces firefly habitat quality measurably; the darker interior parks (Latourette, High Rock, [[mount-loretto-unique-area|Mount Loretto]]) hold higher densities.
