Glacier Springtail
A tiny, elongate springtail adapted to life on glaciers and permanent snowfields. It is dark-pigmented to absorb solar radiation. Populations can be found actively hopping on glacier surfaces in summer.
Did You Know?
This springtail can survive being encased in ice and resume activity once temperatures rise above freezing.
Two-toothed Goldenring
A large, dark goldenring dragonfly of central European mountain streams. It is distinguished from other goldenrings by two tooth-like projections on the occipital triangle.
Did You Know?
Its larvae develop in tiny trickles of spring water no wider than a hand, unlike most large dragonflies.
