Rosy Apple Aphid

Rosy Apple Aphid

A small, dusty pink to purplish-gray aphid that clusters on apple foliage in spring, causing distinctive curled, reddened leaves that make its presence easy to spot even before the insects themselves are seen.

true-bug
Soldier Beetle

Soldier Beetle

A slender, soft-bodied beetle in orange and black or yellow and brown, often seen clustered on late-summer flowers where it feeds on pollen, nectar, and small insects.

beetle
Codling Moth

Common House Spider

Common House Spider

Tucked into a messy tangle of silk in a quiet corner, the common house spider is one of the most familiar indoor spiders, quietly picking off flies and other small insects that blunder into its web.

spider

Yellow Dung Fly

A golden, densely furred fly whose bright males cluster on fresh cow pats in pastures, competing for mates while ambushing smaller insects drawn to the same spot.

fly

wasp

Giant Weta

One of the world's heaviest insects, a giant flightless cricket relative endemic to New Zealand that has survived for millions of years by filling the ecological role usually taken by small mammals.

grasshopper-cricket
Screwworm Fly

Screwworm Fly

A metallic blue-green blowfly whose larvae are unusual among maggots for feeding on living tissue rather than carrion, drawn to even small open wounds on warm-blooded animals. The species has been the target of one of the most successful large-scale insect eradication campaigns in history across much of North America.

fly
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.

fly

Snipe Fly

A slender, long-legged fly often seen perched head-down on a sunny tree trunk or fence post, patiently watching for smaller insects to ambush. Its tapered, wasp-like abdomen and habit of resting motionless with legs splayed give it a distinctive, almost sentry-like posture in woodland clearings.

fly
Fruit Fly (Mediterranean)

Fruit Fly (Mediterranean)

A small but strikingly patterned fly with mottled, banded wings held out to the sides in a fan and a body dotted with silvery spots, best known for larvae that tunnel through ripening fruit. Native to sub-Saharan Africa, it has spread with human trade to become one of the most widely recognized fruit-infesting insects in the world.
