Cuckoo Bee
A slender, wasp-like bee that lacks pollen-carrying hairs because it never gathers its own pollen, instead sneaking into the nests of other solitary bees to lay eggs that hatch and consume the host's food stores.

Bagworm Moth
A moth best known for its larva's habit of constructing and living inside a spindle-shaped case of silk and plant debris that hangs from twigs, with adult males a plain sooty-winged moth and females remaining wingless and grub-like inside the bag for life.

Marsh Fly
A slender, unassuming fly best known for larvae with a remarkable diet: nearly every species in the family feeds on aquatic or terrestrial snails and slugs, making marsh flies natural specialists in wetland food webs. Adults are often found resting quietly on sedges and other marsh vegetation near the water's edge.
