Dragonhunter
North America's largest clubtail, the Dragonhunter is a powerful predator that lives up to its name by capturing and eating other dragonflies, including species nearly its own size.
dragonflyGiant Centipede
A long, fast-moving, many-legged predator with a hardened segmented body and a pair of venom-injecting claws behind the head that it uses to overpower prey far larger than itself.
myriapod
Dragonfly Nymph
A stocky, camouflaged underwater predator that spends months or years stalking prey along the pond bottom before transforming into an aerial dragonfly.
aquatic-insect
Vinegaroon
A robust, dark, scorpion-like arachnid whose long, thin whip for a tail gives it its name, and whose signature defense is spraying a concentrated mist of vinegar-scented fluid rather than stinging. Despite its intimidating look, it has no venom at all.
arachnid
Diving Beetle
A smooth, streamlined, dark-bodied beetle with broad, fringed hind legs built for swimming, an active underwater predator that carries its own air supply beneath its wing covers.
aquatic-insectSnakefly
A slender predator named for its habit of rearing up its long, mobile neck like a tiny cobra when hunting or threatened.
otherNet-winged Beetle
A soft-bodied beetle with broad, ridged wing covers patterned in bold orange or red and black bands, whose netlike wing venation and vivid coloring warn potential predators of its unpalatability.
beetle
Convergent Ladybird Beetle
A common orange-red ladybird with black spots and two distinctive converging white lines on its thorax, widely valued as a natural aphid predator.

Spiny Flower Mantis
A small, boldly patterned mantis whose wing markings resemble a pair of eyespots, flashed open in a startling display whenever a predator ventures too close.
mantis-stick
Giant Asian Mantis
A bulky, leaf-green predator that sits patiently among foliage, its powerful spined forelegs poised to snatch any insect that strays too close.
mantis-stickDamselfly Nymph
A slender aquatic predator with three feathery tail gills, patiently stalking small prey among pond plants before emerging as a delicate flying damselfly.
aquatic-insect
Emperor Scorpion
A massive, glossy black scorpion with heavy, oversized pincers built for crushing prey rather than stinging it, the emperor scorpion is one of the biggest and most recognizable scorpions on Earth. It digs deep burrows in rainforest soil and is unusual among scorpions for tolerating close family groups.
arachnidPhantom Midge Larva
Almost invisible in open water, the phantom midge larva is a slender, transparent predator that drifts through the water column, using a pair of internal gas-filled sacs to hover at precise depths while hunting tiny prey.
aquatic-insectHorse Fly Larva
Hidden in the wet mud along pond and stream margins, the horse fly larva is a tapered, tough-skinned predator that hunts other small soil and mud-dwelling invertebrates before eventually transforming into the familiar biting fly.
aquatic-insect
Lacewing
A delicate, pale green insect with large, transparent, intricately veined wings and shining golden or copper-colored eyes, valued as a natural predator of aphids in its larval form.

Io Moth
A striking yellow (male) or reddish-brown (female) silkmoth instantly recognizable by the large, dark eyespot ringed in blue and black on each hindwing, flashed suddenly to startle predators.
mothGreen Lacewing
With delicate pale green wings and glittering golden eyes, the Green Lacewing is a familiar garden insect whose larvae are voracious predators of aphids and other soft-bodied pests.
otherAnt-mimic Spider
A slender jumping spider that walks on six legs while waving the front pair like antennae, convincingly passing itself off as an ant to fool predators and prey alike.
spider
Centipede
A fast-moving, flattened, many-legged predator with one pair of long legs per body segment, instantly recognizable by its speed and, in the house centipede, its remarkably long, banded legs.
myriapod
Dragonfly
A large, agile aerial predator with an elongated body, enormous compound eyes, and two pairs of strong wings held straight out to the sides at rest, often seen patrolling over water in search of prey.
dragonflyFishfly Larva
A flattened, armor-plated predator of stream bottoms, the fishfly larva spends one to three years underwater seizing prey with sickle-shaped jaws before briefly taking wing as a short-lived winged adult.
aquatic-insect
Great Diving Beetle
One of Europe's largest water beetles, the great diving beetle is a streamlined, olive-brown predator that rows through ponds on fringed hind legs, surfacing periodically to trap a bubble of air beneath its wing covers.
beetle
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
Boll Weevil
A small, grayish-brown snout beetle with a long, curved rostrum, historically famous for its close feeding association with cotton flower buds and bolls.
