Birch Leaf-Roller Sawfly
A flat-bodied sawfly with long, thread-like antennae and a broad abdomen. Larvae roll birch leaves into tubes using silk and feed inside these shelters.
Did You Know?
The larva creates an elaborate rolled-leaf shelter that protects it from both predators and weather while it feeds inside.
Spined Sweat Bee
A brilliantly iridescent green sweat bee with bluish reflections found in the eastern United States. Both sexes are entirely metallic green, unlike many other Agapostemon species.
Did You Know?
It strongly prefers nesting in moist or damp soil near water, unlike most other sweat bees that prefer drier substrates.
