She appears to be displacing the native Carolina mantis (Stagmomantis carolina) across overlapping US range — a controversial 'beneficial' species.

Cottony cushion scale almost destroyed the California citrus industry in 1888 — most groves from San Diego to Sacramento were infested and many were abandoned.

USDA entomologist Albert Koebele imported 130 vedalia ladybeetles from Australia in 1888 — within 18 months they had saved the California citrus industry.

The vedalia / cottony cushion scale program founded the entire field of classical biological control — the most-cited biocontrol case in agricultural history.

The 'cottony cushion' name describes the species' distinctive fluted white waxy egg sac that protrudes from the rear of the female scale insect.

Albert Koebele's expedition to Australia in 1888 to find natural enemies of cottony cushion scale established the modern playbook for classical biocontrol expeditions.

The crab louse host-jumped from GORILLAS to early hominins approximately 3-4 million years ago — a textbook case of parasite host-switching in molecular anthropology.

The 'crab' name comes from the wide flattened body shape and strong claws on the legs that clamp onto coarse hair shafts.

Crab lice are NOT found on the human scalp — the hair-shaft diameter and spacing of head hair does not support crab louse attachment.

Crab louse is in a separate genus (Pthirus) from head/body lice (Pediculus) — the two lineages diverged tens of millions of years ago.

Modern infestation rates have declined sharply since the 1970s — possibly correlated with increased pubic hair removal practices.

Cuckoo bees lay eggs in OTHER bees' nests — their larvae kill the host larva and eat the host's pollen-and-nectar provisions.

About 15% of all bee species worldwide are cuckoo bees — ~3,000 of the ~20,000 known bee species use this kleptoparasitic strategy.

Cuckoo bees lack the dense pollen-collecting hair of true bees — typically wasp-like in appearance, easily mistaken for small wasps.

The cuckoo bee strategy independently evolved 4+ times in different bee lineages — convergent with the cuckoo bird's brood parasitism.

Cuckoo bee populations depend entirely on host species populations — making them a useful indicator of solitary bee community health.

Emperor dragonfly is the largest dragonfly in Europe — 8 cm body, 11 cm wingspan.

Emperor dragonfly hunting success rate exceeds 95% — far higher than any large vertebrate predator (lions ~25%, hawks ~30%, sharks ~50%).

She catches and eats prey ENTIRELY in flight — the legs form a basket, the prey is consumed midair without landing.

Adult flight speed reaches 50+ km/h in level pursuit — among the fastest insects in level flight.

Aquatic naiads spend 1-2 years as voracious predators of mosquito larvae, midge larvae, tadpoles, and small fish — major contributors to mosquito control.

Screwworm larvae burrow INTO living tissue of cattle, horses, deer, and other warm-blooded animals — feeding on the flesh until the untreated host dies in 7-14 days.

USDA invented the Sterile Insect Technique (SIT) for screwworm — release billions of irradiated sterile males that mate with wild females and produce no offspring. Population crashes.

The species was eradicated from the southeastern US by 1966, the entire US by 1982, Mexico by 1991, Central America by 2000.

The 1958 USDA mass-rearing facility at Mission, Texas was the first industrial-scale insect mass-rearing operation in human history — producing 50-500 million sterile flies per week.

Today 30-50 million sterile flies are released weekly at the Darien Gap (Panama-Colombia barrier zone) to prevent re-incursion from South America.

The Africanized honey bee originated in 1957 when 26 African queens escaped a Brazilian research apiary and interbred with local European honey bees.

Colonies respond to disturbance with mass attack of hundreds to thousands of stings — pursue intruders 400+ meters and remain agitated for hours.

Estimated cumulative human deaths from Africanized honey bee attacks since 1957 exceed 1,000 across the Americas.

The hybrid spread northward from Brazil at ~500 km/year — reached southern Texas in 1990 and now occurs across most of the southern US.
