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.
Walnut Sphinx Moth
A beautifully cryptic hawk moth with scalloped wing edges and mottled brown, gray, and lavender patterns. It rests among leaf litter where it is nearly impossible to detect.
Did You Know?
The walnut sphinx caterpillar can produce a high-pitched whistle by forcing air through its spiracles, startling birds and other predators.
