Monkey-puzzle
The Monkey-puzzle tree is unmistakeable with its pyramidal shape, jutting branches and stiff, dark green 'spines' (its leaves). Widely planted in the UK's parks and gardens, it is threatened globally.
Montagu's blenny
A small fish found on rocky shores in the south and west of Britain.
Montagu’s sea snail
Although, commonly referred to as a ‘sea snail,’ this species in fact belongs to the fish family!
Moon jellyfish
The moon jelly is the most common jellyfish in UK seas, often washing up on our beaches. No need to worry though - it doesn't sting humans.
Moorhen
A familiar black bird of our lakes, ponds and rivers, the moorhen is widespread; look out for its large and untidy-looking nest on the water in spring. It can be distinguished from the similar coot by its yellow legs, red beak and the white patches on its body.
Morel
This unique fungus is one of the most sought after spring fungi of them all.
Mother Shipton
This striking day-flying moth is named after a 16th century witch.
Mottled grasshopper
The Mottled grasshopper can be found in dry grasslands, such as railway cuttings, and heathlands throughout summer. Males can be seen rubbing their legs against their wings to create a 'song' for the females.
Mouse-ear hawkweed
Looking a bit like a ragged version of a dandelion, mouse-ear hawkweed has lemon-yellow flower heads that are tinged with red at their outer edges. It likes grassy places with short turf and chalky soils.
Mullein
You're more likely to see the attractive, brightly coloured caterpillars than the mullein moth itself.
Muntjac deer
The muntjac deer was introduced into the UK from China in the 20th century. It has gained a stronghold in southeast England, where it can cause damage to our woods through browsing.
Musk beetle
The metallic-green Musk beetle lives up to its name: it releases a musky-smelling secretion when it defends itself. It is a longhorn beetle, so has lengthy antennae. Look for it near wetlands in summer.
