Whirligig Beetle
A small, oval, shiny black beetle that spins in rapid circles on the water surface. Its eyes are divided in two, allowing it to see above and below water simultaneously.
Did You Know?
Whirligig beetles have uniquely split compound eyes, with one pair looking above the waterline and another pair looking below it at the same time.
Brassy Willow Beetle
A small, shiny metallic bronze to greenish beetle that feeds on willow and poplar. Adults overwinter in leaf litter and emerge in spring to colonize new willow growth.
Did You Know?
Larvae secrete salicylaldehyde, a chemical obtained from salicin in willow leaves, which smells like antiseptic and deters predators.
