The federal Mexican Bean Beetle Biocontrol Program uses parasitoid wasps from the species' Mexican home range as biological control agents.

The Mormon cricket is NOT a cricket — she's a wingless shieldback katydid (family Tettigoniidae).

She marches in massive bands of millions across western US rangeland — kilometer-long bands consuming everything in their path.

The 1848 'Miracle of the Gulls' incident commemorates seagulls saving the first Mormon Utah harvest from a Mormon cricket invasion — seagull is now Utah state bird.

Cannibalism drives the marching — individuals at the front of the band move forward to escape being eaten by those behind.

Modern outbreaks across the western US cause tens of millions of dollars in rangeland damage in bad years — most recently 2003-2010 and 2021-2024.

The multicolored Asian lady beetle was deliberately released in North America by USDA between the 1960s-1990s as biocontrol — but became invasive.

She has displaced multiple native North American ladybeetle species — Coleomegilla maculata, Coccinella septempunctata, and others.

Autumn aggregations of 10,000+ beetles enter buildings seeking overwintering sites — major nuisance pest in eastern and central North American homes.

When threatened she 'reflex bleeds' foul yellow alkaloid hemolymph from leg joints — stains carpets and walls when crushed.

Even small numbers of crushed beetles in a wine vat impart a distinctive 'ladybug taint' (methoxypyrazines) that ruins commercial wine batches.

The odorous house ant smells like rotten coconut or blue cheese when crushed — a pyrazine-and-methyl-ketone defensive secretion.

Like pharaoh ants, odorous house ants BUD when stressed by spray — workers and brood split off to establish new satellite colonies.

Colonies can reach hundreds of thousands of workers with hundreds of queens — defeating standard chemical control.

The odorous house ant is the most common indoor ant in North America — and one of the few major indoor ant pests that is NATIVE rather than invasive.

The only effective control is slow-acting bait that workers carry back to the queens — never spray odorous house ants.

The oriental rat flea has killed an estimated 200+ million humans across history — the most consequential insect in human history.

The 14th-century Black Death killed 30-60% of Europe — 75-200 million deaths across Eurasia in 7 years (1346-1353).

Y. pestis blocks the flea's foregut so she cannot feed — she bites repeatedly and regurgitates the bacterial block into each bite wound.

Plague is still endemic — 10-15 US cases per year in the western states, plus thousands of cases per year in Madagascar, Mongolia, and central Africa.

Three pandemics: Justinian Plague (542 CE), Black Death (1346-1353), and Third Pandemic (starting 1855) — together the deadliest disease event series in human history.

The two-spotted spider mite damages over 1,100 documented host plant species — among the broadest diet ranges of any agricultural pest.

The 2011 genome reveals over 1,000 detox genes — far more than typical animals — explaining her ability to defeat almost every miticide chemistry.

She is just 0.5 mm — barely visible to the naked eye, hides on the underside of leaves where damage is hardest to detect.

Despite the name, she is NOT a true spider — class Arachnida, but order Trombidiformes (mites), not order Araneae (true spiders).

Damaged leaves develop characteristic stippling, then yellowing, bronzing, and finally complete defoliation in heavy infestations.

Caddisfly larvae build PORTABLE cases from grains of sand, twigs, stones, snail shells, and leaf fragments — glued together with silk.

French artist Hubert Duprat provided larvae with gold leaf, pearls, and precious stones in the 1980s — they built actual gold-and-gemstone cases now exhibited in major museums.

Caddisflies (order Trichoptera) are the closest living relatives of moths and butterflies — sister group to Lepidoptera in the insect phylogeny.

There are about 14,500 species of caddisfly worldwide — most aquatic, with extraordinary diversity of case-building architectures.
