Asian tiger mosquito vectors dengue (all four serotypes), chikungunya, Zika, yellow fever, and several less-common arboviruses.

American burying beetles practice biparental care — both male and female remain in the brood chamber and feed regurgitated meat to the larvae for 1-2 weeks.

The pair buries small vertebrate carcasses (mice, voles, bird young) by digging soil out from under — the carcass sinks into a chamber, then meat is treated with antimicrobial secretions.

Federally listed as Endangered in 1989 after collapsing across 90% of historical range — declined to a single Block Island, Rhode Island population by the 1980s.

Captive breeding and reintroduction programs since 1994 restored populations to multiple states — downgraded from Endangered to Threatened in 2020.

She is the largest North American burying beetle — 25-35 mm body length, brilliant red-and-black coloration.

Red-blue checkered beetle adults have brilliant metallic blue elytra patterned with three bold red transverse bands — among the most beautiful European beetles.

Larvae hitchhike on FORAGING BEES back to the bee's nest — then eat the bee's developing brood and pollen provisions.

Family Cleridae contains about 3,500 species worldwide — most are similarly bee or wasp brood parasitoids using host-hitchhiking strategies.

Adults are major flower-visiting pollinators of yarrow, daisies, and other meadow composites — beneficial role despite the larval parasitism.

The species is ecologically complex — beneficial as an adult pollinator, harmful as a larval parasitoid of agriculturally-important Megachile leafcutter bees.

European garden spider abdomens carry a distinctive white CROSS-shaped pattern of dorsal spots — the source of medieval folklore interpreting the marking as the cross of Christ.

She rebuilds her orb web every night — the old web is consumed in early morning to recycle the silk proteins, and a new web is built within an hour the following evening.

Two European garden spiders (named Anita and Arabella) were the first spiders sent to space — NASA Skylab 3 in 1973. Both built almost-normal webs in microgravity.

Garden spider dragline silk has tensile strength comparable to high-tensile steel by weight — and elasticity allowing 30-40% stretch before breaking.

She is the textbook example of orb-web building behavior — featured in nearly every introductory biology textbook discussion of spider webs.

Common green darner is one of the largest dragonflies in North America — 8 cm body, 11.5 cm wingspan.

Annual multi-generational migration spans 1,500+ km between northern Canada/US ponds and southern Mexico/Caribbean overwintering.

Migration spans THREE successive generations — spring migrants north, summer offspring stay/move further north, autumn third generation flies south.

Adults are voracious mosquito predators — major beneficial insects for mosquito control. Naiads similarly take mosquito larvae and tadpoles.

The 2018 Hallworth et al. paper used stable hydrogen isotope analysis of wing tissue to definitively prove the multi-generational migration pattern.

Sawflies are the most ancient surviving lineage of Hymenoptera — predating wasps, bees, and ants by approximately 230 million years.

Female sawflies have a saw-shaped ovipositor used to CUT SLITS in plant tissue for egg-laying — the basis of the 'saw' common name.

Sawfly larvae look like caterpillars but have 6+ pairs of prolegs — Lepidoptera caterpillars have 5 or fewer. Easy field-ID difference.

Birch sawfly larvae produce a powdery hydrophobic wax that they spread over their bodies — protection against rain and predators.

When threatened, larvae rear up and spray a sticky defensive fluid from glands beside the head — similar mechanism to velvet worm slime defense.

Ten-lined June beetle is the largest scarab beetle in western North America — adults reach 30-35 mm.

When grabbed, the beetle rubs her abdomen against a ridge on the elytra to produce a piercing audible squeak — startles predators into releasing her.

Males have dramatic feathered antennae — each terminates in a fan-like cluster of 7 large lamellae used for detecting female pheromones from significant distances.

The species name 'decemlineata' means 'ten-lined' — for the ten cream-white longitudinal stripes on the elytra.
