Distinctive black mosquito with white lyre-shaped markings on thorax. Primary vector of dengue, yellow fever, Zika, chikungunya in tropical Asia.

Dengue: 4 billion at risk globally, 40,000 deaths/year, mostly in Asia. 2024 outbreak in Bangladesh killed 1,705. Bangkok, Manila, Karachi seasonal epidemics.

Urban areas of all tropical and subtropical Asia. Domestic breeder — flowerpots, water tanks, gutters, AC drips.

Daytime biter (unlike most mosquitoes). Bites multiple people per blood meal — spreads disease efficiently.

5-7 mm mosquito. The primary vector of malaria in urban South Asia. As a species group, mosquitoes have killed more humans than any other animal in history.

Malaria kills 600,000+ people/year globally — most in tropical Asia and Africa. Dengue, lymphatic filariasis, Japanese encephalitis also transmitted. India: 200,000+ malaria cases/year.

Urban and peri-urban areas of India, Pakistan, Bangladesh, Myanmar, Thailand, Indonesia, parts of Middle East, Horn of Africa.

Bites at dusk and dawn. Breeds in wells, water storage containers, construction sites. Now spreading to African cities.

Largest hornet in the world — up to 5 cm with 6 mm stinger. Orange head, yellow-black banded body. Killed enough Americans in 2020 to earn nickname 'murder hornet'.

Sting delivers high-volume venom that destroys flesh. 30-50 deaths/year in Japan alone, mostly from anaphylaxis or multi-sting attacks. Can sting repeatedly.

Japan, Korea, China, Taiwan, eastern Russia, India, Nepal, Thailand, Vietnam. Forests, mountains, low elevation farmland.

Hunts honeybee colonies — a single hornet can kill 40 bees per minute. Attacks human nests aggressively at 5 m radius.

Up to 200 kg. Black with distinctive white V on chest ('moon bear'). More aggressive toward humans than American black bear.

Highest rate of unprovoked attacks among any bear species. Japan: 5-15 deaths/year, India: 10+ deaths in Kashmir alone. Mauls — targets face and head.

Forests from Iran east through Pakistan, India, Nepal, Bhutan, China, Japan, Russian Far East, Vietnam, Taiwan, Korea.

Mostly solitary, partly arboreal. Hibernates in north. More day-active than other bears. Attacks if cornered or with cubs.

Brown mosquito 5–7 mm — the typical 'house mosquito' across Europe. Native, not invasive — but increasingly dangerous as warming climate amplifies disease cycles.

Primary vector of West Nile virus in Europe. Italy alone logged 430 WNV cases and 27 deaths in summer 2025 — equal to all US cases for that year. Spain, Greece, France, Romania, Hungary all reporting outbreaks.

All of Europe except the far Arctic. Breeds in any standing water — gutters, water butts, flooded basements, urban drains.

Bites mostly at dusk and night. Females hibernate in basements/attics through winter. The lifecycle from egg to adult takes only 7–10 days in summer.

Small, dark tick — the primary disease vector in Europe. Despite being only 3–4 mm, kills more Europeans annually than any other animal.

Transmits Lyme borreliosis (200,000+ cases/year), tick-borne encephalitis (3,500+ cases/year, ~30 deaths), babesiosis, anaplasmosis. The TBE vaccine exists.

Forests, parks, tall grass, urban green spaces. Most active April–June and September–October.

Quests on grass tips and twigs, latching on contact. Seeks warm, moist body sites. Feeds for 3–7 days before dropping off.

Up to 65 cm. Brown with darker oval blotches. The most common venomous snake in Japan — causes ~3,000 bites/year with 5-10 deaths.

Hemotoxic venom causes severe pain, swelling, occasionally kidney failure. Antivenom available; deaths now mostly elderly or untreated cases.

Forests, mountains, rice paddies of Japan (all main islands), Korea, China, eastern Russia.

Mostly diurnal in spring/autumn, nocturnal in summer. Often basks on stone walls. Used in traditional medicine — preserved in sake.

Up to 80 cm. Olive-brown body. The famous fugu — its liver, ovaries and skin contain tetrodotoxin, 1,200x more deadly than cyanide. Eaten as expensive delicacy in Japan.

TTX has no antidote. Causes paralysis with full consciousness — victims aware but unable to move or breathe. Treatment: ventilator until toxin clears. 50-100 cases/year in Japan, 5-10 deaths.

Coastal waters of Japan, Korea, China, Taiwan. Cultivated in special farms for restaurant trade.

Slow swimmer relying on toxin defense. Inflates when threatened. Licensed fugu chefs train 3+ years to safely prepare.
