Milky spore disease (Paenibacillus popilliae) is a microbial pesticide SPECIFIC TO Japanese beetle larvae — a flagship example of biological control of an invasive pest.

Pandora sphinx larvae have FIVE OVAL WHITE-RIMMED EYE-LIKE SPOTS along each side of the body — looking like a green or pink SNAKE with multiple eyes. One of the most-cited cases of larval eye-spot mimicry in NA Lepidoptera.

Adult wings have a complex CAMOUFLAGE PATTERN — olive-green-to-grayish-brown with graduated bands of pink, cream, and black resembling dappled forest light on tree bark.

Larvae are color-polymorphic — variants include bright green, pink, and brown forms, sometimes all three in the same population.

When threatened, larvae withdraw the head deep into the thoracic segments — making the eye-spots appear larger and more prominent. Defensive 'snake mimicry display'.

Larvae feed on grape and Virginia creeper leaves — both common landscape plants in eastern North America. Adults are major beneficial pollinators of nocturnal flowers.

Single large WHITE-OR-SILVER OVAL SPOT on the underside of each hindwing — flashes brightly in flight as the butterfly raises and lowers the hindwings.

Skippers (family Hesperiidae) are a distinct LINEAGE within Lepidoptera — historically classified as butterflies but molecular phylogenetics has shown they form a distinct sister lineage to the 'true' butterflies.

Skippers commonly rest in 'JET PLANE' posture — forewings held up at an angle, hindwings flat. Not seen in other Lepidoptera; one of the most-cited field-ID features for distinguishing skippers from butterflies.

Rapid darting flight ('skipping' from flower to flower) is the source of the common name. Stout muscular body and hooked antennae also distinguish skippers from butterflies and moths.

Larvae construct distinctive LEAF SHELTERS — webbing together leaves of the host plant with silk to create small enclosed shelters where the larva rests during the day.

Carolina grasshoppers reveal dramatic BLACK HINDWINGS BORDERED BY CREAM-OR-WHITE in flight — flash coloration creates a visual pattern strikingly similar to a black-and-white butterfly.

Produces audible CRACKLING or hand-clapping sound from the wings during flight ('crepitation') — the front wings snap against the hindwings during wing-beats.

PERFECTLY camouflaged at rest — grayish-brown to dirt-colored markings make her essentially invisible against bare soil, dirt roads, and barren ground.

The combined VISUAL FLASH + AUDIBLE CRACKLE creates a startle display interpreted as anti-predator — disrupting bird and small-mammal predation attempts before they can be completed.

Prefers disturbed bare-ground habitats — dirt roads, fence lines, recently-burned areas, gravel parking lots. Not a crop pest.

The differential grasshopper's diagnostic field-ID feature is a HERRINGBONE PATTERN of black markings on the hind femora — distinguishing it from other Melanoplus species.

Outbreak populations cause TENS TO HUNDREDS OF MILLIONS of dollars in agricultural losses across the central US — corn, sorghum, alfalfa, wheat, vegetable crops.

Major culprit in 1930s Dust Bowl crop devastation — grasshopper outbreaks contributed substantially to the agricultural collapse of the central US during the dust bowl years.

2010 Wyoming outbreak caused tens of millions of dollars in losses — grasshopper densities reached 50-100 individuals per square meter across thousands of square kilometers of rangeland.

Females lay eggs in SOIL PODS — clusters of 50-150 eggs deposited in undisturbed grassland or fence-row soil that overwinter and hatch in spring as next generation.

Gulf fritillaries have BRILLIANT METALLIC-SILVER-AND-CREAM SPOT PATTERNS on the underside of the hindwings — created by structural coloration, the spots flash dramatically with every wingbeat.

She is a HELICONIINI — same tribe as the tropical longwing butterflies (zebra longwing, postman butterflies). Shares the longwing biology of warning coloration and toxin sequestration.

Larvae feed EXCLUSIVELY on passion flowers (Passiflora species) — they sequester the toxic CYANOGENIC GLYCOSIDES and retain the toxicity through pupation into the adult stage.

Adults are CHEMICALLY DEFENDED — bird predators learn (after one or two unpalatable encounters) to avoid the bright orange-and-black warning coloration.

Adult heliconiine butterflies including Gulf fritillaries can feed on POLLEN as well as nectar — a behavior UNIQUE to heliconiine butterflies among Lepidoptera, providing protein for extended adult lifespan.

Jerusalem crickets have a HUGE BULGING HEAD that is disproportionately large compared to the body and looks unsettlingly HUMAN-LIKE in shape — the source of the 'potato bug' and 'child of the earth' common names.

Jerusalem crickets are NOT true crickets (family Gryllidae) and not from Jerusalem — the common name origin is unclear and possibly a corruption of an indigenous word or early naturalist label.

Produces a creepy-sounding scratching/chirping by rubbing the abdomen against the hind legs — one of the few non-true-cricket Orthoptera that stridulates.

Males produce a low DRUMMING by tapping the abdomen against the substrate to call females — similar to the percussive mating calls of click beetles and some moths.
