One of our largest and most impressive solitary wasps, the bee wolf digs a nest in sandy spots and hunts honey bees.

The branching, finger-like projections of this fungus give it the appearance of an underwater coral. Its striking colour and form make it easy to spot, but it is scarce in the UK.

Red squirrels are native to the UK but are a lot rarer than their grey cousins. They live in a few special places across the UK thanks to reintroduction projects.

The UK's largest native grasshopper is also one of its rarest, found only on wetlands in a few parts of England.

Ground-elder was likely introduced into the UK by the Romans and has since become naturalised. A medium-sized umbellifer, it is an invasive weed of shady places, gardens and roadsides.
