Thrips are small hemimetabolic insects with a distinct elongated, cigar-shaped body. Their asymmetrical mouth sets them apart. Surprisingly, the right mandible is minimized and may even be absent in some species.

Earwigs are abundant creatures spread across the Americas and Eurasia. Their elongated bodies squeeze into tight crevices, like those found under bark.

Silverfish, a nocturnal insect known for its fish-like shape, lives mostly in the dark. This insect transforms from a white hatchling to a metallic, grayish adult. Key features include two long cerci, a terminal filament, and, in a few species, small eyes.

Mayflies populate the globe in clean freshwater habitats. The adult insects, characterized by their large compound eyes and short antennae, lack functional mouthparts or digestive tracts and hence do not feed in their winged stages.

The Glowworm beetle is an interesting creature. The females exhibit bioluminescence, resembling their larval stage. They cast light through photic organs on each body segment and sometimes from luminous bands extending across the body. These females are spotted more frequently than the larvae.

Tiger beetles thrive in sandy habitats across many continents, notably the United States. They're nimble creatures, quick to take flight and have a near-perfect vision. Their bright hues adorn their bodies, earning them the label "butterflies of the beetle world."
