🍄 FLY AGARIC (Amanita muscaria)
This fairy-tale fungus forms mycorrhizal partnerships with trees, trading nutrients for sugars underground. Its red & white cap signals potent compounds (ibotenic acid & muscimol) that can cause hallucinations and delirium.
Strictly for admiring, not nibbling!

Calliteara pudibunda, the pale tussock moth caterpillar. Brilliant yellow tufts and an ultra-black stripe – a striking warning. When disturbed, it curls into a conker-like ball. Those hairs are likely irritating to the skin, a fine example of visual and chemical defence.

This magnificent ancient oak @kneppwildlandfdn.bsky.social is one of many around the U.K. that are heavy with acorns — a reminder of how oak trees quietly sustain whole worlds beneath their branches. Hundreds of species depend on them: birds, mammals, fungi, lichens, and countless insects.
