Snail-Case Caddisfly
A remarkable caddisfly whose larva builds a coiled sand-grain case resembling a tiny snail shell. Found in warm streams of the American Southwest.
Did You Know?
Cases so closely resemble snail shells that they were originally described as a new genus of freshwater snail.
Granulated Pygmy Grasshopper
A granular-textured pygmy grasshopper found on sandy and gravelly substrates in North America. Its rough body surface enhances its camouflage on coarse soil.
Did You Know?
Its granular body texture is not just for camouflage but also helps regulate moisture absorption from damp substrates.
