Bluet Damselfly
Small and delicate, bluet damselflies flash brilliant blue and black along the vegetated edges of ponds and lakes, forming mating pairs that fly in tandem while laying eggs directly into plant stems underwater.
dragonflyRootworm
Working unseen below ground, rootworm larvae chew tunnels through the root systems of corn and other crops, the underground counterpart to the small, often striped or spotted beetles seen on leaves and flowers above.
beetleSoil Mite
A microscopic, heavily armored mite found by the millions in a single handful of soil, quietly breaking down leaf litter and helping build the fertile ground beneath forests and fields.
arachnidMaggot
A pale, legless, tapering grub that wriggles through rotting food and organic waste, the larval stage of a fly.
caterpillar-larvaHoverfly
A slender, bee- or wasp-patterned fly known for its remarkable ability to hover motionless in midair before darting suddenly to a new flower.
flySand Wasp

moth
Cabbage White
A common, small white butterfly with one or two black wing spots, whose green caterpillars are a familiar sight feeding on cabbage-family garden plants.
butterfly
Meadow Fritillary
A small, fast-flying orange-and-black fritillary of open grassy fields, easily told from its larger cousins by its lack of silvery spots on the underside of the hindwing.
butterflyFirefly
A soft-bodied, dusk-flying beetle famous for the bioluminescent flashes it produces from its abdomen to attract mates on warm summer evenings.
beetle
Blow Fly
A brilliant, metallic green fly that gleams like a jewel in sunlight, quickly locating decaying material with an acute sense of smell.
fly
Tussock Moth
A moth with a striking split lifestyle: winged, drab gray-brown males fly to seek out flightless, grub-like females, while the ornate caterpillars sport dense tufts of colorful bristly hair.
