Modern equine deworming protocols specifically target bot larvae using ivermectin and similar antiparasitic compounds — the species is a continuing equine veterinary concern.

House crickets are produced commercially as human food in over 30 countries since the 1990s — the most globally significant edible insect species.

Crickets are 60-70% protein by dry weight — and cricket farming uses 2,000x less water and 12x less feed per kg of edible protein than beef.

Billions of house crickets are produced annually as 'feeder crickets' for the global pet reptile, amphibian, bird, and arthropod industries.

House cricket chirp rate follows Dolbear's law (1897) — count chirps in 14 seconds, add 40, get approximate temperature in °F.

Native to southwestern Asia but transported globally with human commerce since at least the Roman era — now cosmopolitan.

Queen of Spain fritillary has the LARGEST silver patches on the underside of any European butterfly — dramatic mirror-like reflective spots that flash in flight.

The silver is structural coloration (multilayer reflective scale architecture) — not pigment. The patches appear bright from some angles and dark from others.

The reflective silver patches are believed to function as predator-confusion signals — alternately flashing and dimming during flight to make the butterfly difficult for aerial predators to track.

She is migratory — northbound migrants from southern Europe and North Africa annually reach Britain and Scandinavia, with occasional invasion years pushing populations to Iceland.

Caterpillars feed on violets (Viola species) — similar to other European fritillaries and dependent on violet meadow conservation.

Medieval European Christians named the species 'Our Lady's beetle' for the Virgin Mary — the seven spots represented Mary's Seven Sorrows. Source of English 'ladybird' and 'ladybug.'

A single seven-spot ladybird consumes 5,000+ aphids over her ~1-year adult lifespan — plus thousands more during the larval stage.

USDA deliberately introduced the seven-spot ladybird to North America in 1956 as biological control for aphid pests — established widely across the continent.

She has partially displaced native Coccinella species in North America — especially the nine-spotted ladybird (C. novemnotata), now rare across much of its former range.

Seven black spots arranged in a 1-2-2-2 pattern — one large central spot at the head end, two pairs of paired spots toward the rear. Iconic.

Stalk-eyed flies have eyes mounted on the tips of long lateral stalks that project out from the head — sometimes wider than the fly's entire body length.

Males have dramatically longer eye-stalks than females — eye-span:body-length ratio 1.5-2.0 in males vs. 0.8-1.2 in females. Extreme sexual dimorphism.

Rival males face off and align eye-stalks side-by-side — the male with measurably longer stalks wins without physical combat. Pure visual size comparison.

Eye-stalk length is condition-dependent — males in poor condition develop shorter stalks than well-fed males, ensuring honest signaling of male quality.

Family Diopsidae contains about 160 species worldwide — most share the dramatic eye-stalk morphology and many show similar sexual selection patterns.

Male banded demoiselles have a dramatic dark blue iridescent band across each wing — central region of each forewing and hindwing.

She is one of the most-cited freshwater bioindicators in European stream ecology — naiads require low pollution, high oxygen, and clean substrate.

Territorial males perform elaborate fluttering courtship displays in front of approaching females — emphasizing the iridescent wing bands.

Females evaluate male display quality before accepting a mate — one of the most-studied female-choice systems in Odonata.

Rejected males engage in 'sneaker' mating tactics — attempting copulation with already-mated females during the female's egg-laying period.

The brimstone butterfly is widely cited as the species that gave English the word BUTTERFLY — Old English 'buttorflēoge' originally referred to the bright butter-yellow male.

Brimstone adults live up to 11-12 months — among the longest-lived butterflies in Europe. Overwinter as adults in evergreen vegetation.

Leaf-shaped wings with pointed tips at both forewing and hindwing apices — perfect cryptic camouflage in evergreen foliage when folded at rest.

She overwinters as an adult in holly and ivy — flies on warm winter days, mates in spring, dies in early summer after producing the next generation.
