Dacetine Trap-Jaw Ant
A minute trap-jaw ant with elongate mandibles fringed with specialized hairs used to detect and capture tiny soil-dwelling springtails. Workers are slow-moving, cryptic hunters that stalk prey in leaf litter. Their bodies are covered in bizarre spatulate hairs.
Did You Know?
Their mandible trigger hairs are so sensitive they can detect the vibrations of a springtail walking nearby and snap shut in microseconds.
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.
