Females (14-19 mm body length) are dramatically LARGER than males (5-9 mm) — extreme sexual size dimorphism typical of large orb-weaving spiders.

Polka-dot wasp moths are striking WASP MIMICS — metallic blue-black body with white polka dots and bright red abdomen tip looks unmistakably like a stinging wasp. Predators avoid the harmless moth.

Larvae are the famous ORANGE-AND-BLACK OLEANDER CATERPILLARS — gregarious, voracious, and capable of completely defoliating large oleander shrubs in days during outbreak populations.

Larvae sequester TOXIC CARDIAC GLYCOSIDES from oleander host plants — same general chemistry as monarch butterflies (from milkweed). Retains toxicity through pupation into adult stage.

Originally Caribbean — now widespread across the southeastern US wherever ornamental oleander has been planted. Northward spread tracking the planting of oleander.

Larvae have black tufts of hair on a bright orange body — looking like miniature toothbrushes. Combined with gregarious clustering behavior, the bright warning coloration deters predators.

Tomato hornworm is one of the most economically important GARDEN PESTS in North America — a single mature larva can defoliate a small tomato plant in 1-2 days.

Distinguished from the closely-related tobacco hornworm by HORN COLOR (tomato has BLACK-OR-BLUE horn; tobacco has RED horn) and STRIPE PATTERN (V-shapes vs. diagonal stripes).

Adults have FIVE PAIRS of bright YELLOW SPOTS along the sides of the abdomen — source of the species name 'quinquemaculata' (Latin for 'five-spotted').

Larvae feed EXCLUSIVELY on plants in family Solanaceae — tomato, pepper, eggplant, potato, tobacco, ornamental nightshades. Major host plant constraint.

Closely related to Manduca sexta (the tobacco hornworm) — one of the most important MODEL ORGANISMS in modern insect physiology research, especially olfactory neurobiology and metamorphosis.

Primary NA vector of ROCKY MOUNTAIN SPOTTED FEVER — case fatality rates 5-10% even with prompt treatment, 20-30% without treatment. One of the most lethal tick-borne diseases in NA.

Occasionally implicated in TICK PARALYSIS — neurotoxins in tick saliva cause PROGRESSIVE ASCENDING PARALYSIS that can cause respiratory failure if the tick is not removed.

Also transmits TULAREMIA (Francisella tularensis bacterium) — one of multiple tick-borne diseases the species can vector.

Despite the common name, readily attaches to HUMANS, DOGS, LIVESTOCK, DEER, RACCOONS, and many other vertebrate hosts. One of the most-encountered ticks in NA outdoor recreation.

RMSF actually occurs predominantly in the SOUTHEASTERN US and central states — the Rocky Mountain name is from where the disease was first described in the late 1800s, but the disease center has shifted east.

The apple maggot fly is the FOUNDATIONAL case study in sympatric speciation — speciation occurring in the same geographic location without geographic isolation, driven by ecological host shift.

Host shift from native hawthorn to introduced apple began in the 1860s in the Hudson Valley NY and has spread across NA over 160 years — creating two genetically distinct host races that continue to interbreed.

Wings have intricate black-and-white BANDED PATTERNS that resemble jumping spider markings — males display the wings in territorial standoffs that resemble jumping-spider behaviors. Mimicry of jumping spiders is widely interpreted.

Females puncture young apple fruits and lay eggs inside; larvae tunnel through apple flesh and render fruit unmarketable. One of the most economically important pests of NA apple production.

Apple fruits ripen ~3 WEEKS EARLIER than hawthorn fruits — partially TEMPORALLY ISOLATING the two host races even though they live in the same geographic locations and forest habitats.

The dragonhunter is the LARGEST clubtail dragonfly in North America — 8-9 cm body length, 11 cm wingspan. Substantially larger than other gomphid clubtails.

Dragonhunters REGULARLY HUNT AND EAT OTHER DRAGONFLIES as primary prey — eastern pondhawks, common whitetails, twelve-spotted skimmers, flame skimmers, other gomphid clubtails are documented prey.

She is one of the few documented dragonfly predators of TOXIC MONARCH BUTTERFLIES — powerful jaws can crush monarch wings before the butterfly deploys its chemical defense.

Hunts by PERCH-AND-PURSUE — perches on waterside substrates, watches for passing dragonflies, launches into high-speed pursuit flight to intercept and seize prey mid-air.

Naiads develop in stream and river substrates over 2-3 years — equally voracious aquatic predators of small fish and other aquatic invertebrates.

Males have completely BLACK WINGS (both forewings and hindwings entirely jet-black, with no transparent patches) — one of the most striking damselflies in North America.

Adult males have brilliant METALLIC EMERALD-GREEN-AND-BLUE BODIES — the body iridescence shifts between green and blue depending on viewing angle and lighting (structural coloration).

Females have small WHITE WING SPOTS (the 'pterostigma') at the wing tips — diagnostic field-ID feature for distinguishing female ebony jewelwings from other Calopteryx species.

Males perform 'WING-CLAP' DISPLAYS — rapidly opening and closing the wings to flash the iridescent body coloration against the black wings as courtship signal to females.
