Humpbacked Mite-hunter
A diminutive scydmaenine rove beetle with a distinctly humped profile and long, clubbed antennae. It specializes in hunting oribatid mites in the micro-habitats of forest floor detritus.
Did You Know?
To overcome the mite's armor, this beetle first gnaws a small hole in the mite's exoskeleton, then inserts its mandibles to extract the soft tissues inside.
Japanese Oakblue
A beautiful lycaenid butterfly with brilliant metallic blue upperwings and cryptic brown underwings. Found in oak forests where its larvae live in association with ants. Known as 'murasaki-shijimi.'
Did You Know?
The caterpillars produce sweet secretions that attract ants, which then guard them from predators in a mutualistic relationship.
