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.

Up to 1.7 m. Brown with characteristic three rows of dark oval blotches. Considered the deadliest snake species by human mortality — causes the most deaths of any snake worldwide.

Across the Indian subcontinent — India, Pakistan, Bangladesh, Sri Lanka, Nepal. Common in agricultural areas, villages, near water.

Mostly nocturnal. Lies motionless on leaf litter — perfect camouflage. Often bitten by rubber plantation workers.

Up to 75 kg. Tawny gold with black rosettes. India has ~12,000 leopards — many living near human settlements, leading to frequent conflicts.
