Whitefly

Whitefly

A tiny, moth-like white insect that clusters on the undersides of leaves and bursts into a snowy cloud when the plant is disturbed. Despite the name, it is not a true fly but a sap-feeding relative of aphids and scale insects.

true-bug

Follicle Mite

An elongated, microscopic mite shaped almost like a tiny worm, living deep within hair follicles and oil glands of mammal skin where it spends its entire life largely unnoticed.

arachnid
Flame Skimmer

Creeping Water Bug

Broad, oval, and flattened like a tiny shield, the creeping water bug crawls methodically through submerged vegetation rather than swimming freely, using its stout, raptorial front legs to seize prey.

true-bug

Louse Fly

A flattened, leathery-bodied fly that clamps onto fur or feathers with stout claws and scuttles sideways like a tiny crab rather than taking flight when disturbed. Several species shed their wings for good once they settle on a permanent host, spending the rest of their lives buried in fleece or plumage.

Long-Legged Fly

Long-Legged Fly

A jewel-bright little fly that flashes metallic green, blue, or bronze in the sunlight as it darts across leaves on comically long, stilt-like legs, pausing to perform quick territorial displays. Both adults and larvae are active hunters of even smaller insects, making this tiny fly a useful predator in gardens and wetlands alike.
