Erz-Kanalläufer

<em>Amara aenea</em>, the common sun beetle, is a carabid ground beetle in the family Carabidae, order Coleoptera. It is broadly distributed across Europe and has been introduced to North America, typically inhabiting open, sunny habitats such as arable fields, grasslands, sandy heathlands, and disturbed ground with sparse vegetation. Adults are omnivorous, feeding on seeds, small invertebrates, and plant material, and are considered important predators of weed seeds in agricultural systems. <em>Amara aenea</em> is surface-active during warm, dry conditions, typically exhibiting peak activity in late spring and summer. Like many carabid beetles, it is nocturnal and shelters under stones and debris during the day. Larvae develop in the soil, where they also feed on organic matter and small invertebrates. Biological traits including precise adult lifespan, body length measurements, and detailed prey preferences remain poorly documented at the species level. The species is assessed as Least Concern by the IUCN, reflecting its wide distribution, high adaptability to disturbed environments, and no significant known threats to global population status.

Zimtblättriger Birken-Wasserkopf

Cortinarius subbalaustinus is a medium-sized, web-capped mushroom with rusty-brown coloring and a cortina veil characteristic of the large Cortinarius genus. It grows in deciduous and mixed forests forming ectomycorrhizal associations with oak and related hardwood trees in temperate Europe. This fungus exchanges nutrients with tree roots and produces fruiting bodies in autumn.
