Arctic Psyllid
A tiny, winged sap-sucking insect that feeds on willow in Arctic and subarctic regions. Adults are brownish with transparent wings and can jump powerfully using enlarged hind legs. Nymphs produce waxy secretions.

Two-spotted Stink Bug
A colorful predatory stink bug with bold red or orange and black markings. It is particularly valued for its appetite for Colorado potato beetle larvae. The color pattern is variable but always includes two dark spots on the pronotum.
