List of 8-letter Insects that start with S

1

Scorpion

Scorpiones (order — many species)

An ancient arachnid with venomous tail and pincered front claws — among the oldest land animals on Earth (430 million years), with surprising longevity and bizarre fluorescence under UV light.

2

Stinkbug

Pentatomidae (family)

A shield-shaped insect with foul-smelling defensive chemicals — including the brown marmorated stinkbug, an invasive Asian species that has become a major American agricultural pest since its 2001 detection in Pennsylvania.

3

Stonefly

Order Plecoptera (multiple British species)

An ancient aquatic insect whose larvae are the gold standard of clean water — stonefly larvae require highly oxygenated, cold, unpolluted streams to survive, making them invaluable biological indicators of water quality; adults are drab, flat-winged insects that rest on bankside stones and vegetation, rarely flying far from the stream where they developed; one of the most ancient insect orders, with fossils over 300 million years old.
