Common pipistrelle
The common pipistrelle is so small, it can fit into a matchbox! Despite its size, it can easily eat 3,000 insects a night: look for it flitting around the garden or a lit lamp post as it chases its prey.
Common polypody
The common polypody is a hardy fern of damp, shady places in woodlands. It also makes a good garden fern. It has ladder-like, leathery foliage with pimply undersides - these spots are the spores.
Common pond skater
The common pond skater can be seen 'skating' over the surface of ponds, lakes, ditches and slow-moving rivers. It is predatory, feeding on small insects by detecting vibrations in the water's surface.
Common poppy
Once considered a weed of cornfields, the Common poppy is now in decline due to intensive agricultural practices. It can be found in seeded areas, on roadside verges and waste ground, and in field margins.
Common prawn
The common prawn is a familiar sight to anyone who has spent time exploring rockpools - particularly their characteristic quick dart into the darkness just as you spot them!
Common puffball
This common fungus puffs out clouds of spores when it's mature.
Common ragwort
A renowned 'weed' of paddocks, pastures and waste ground, the yellow flower heads of common ragwort are actually highly attractive to bees and other insects, including the cinnabar moth.
Common red soldier beetle
The common red soldier beetle is also known as the 'bloodsucker' for its striking red appearance, but it is harmless. It is a beneficial garden insect as the adults eat aphids, and the larvae eat other pests.
Common reed
The extensive, golden-brown reedbeds that are formed by stands of Common reed are a familiar sight in our wetlands. They provide an important home for many species, including the rare Bittern.
Common restharrow
Look for the small, pink, pea-shaped flowers of Common restharrow on chalk and limestone grasslands, and in coastal areas, during summer.
Common rock-rose
Golden banks of common rock-rose make a spectacular sight on our chalk and limestone grasslands in summer. A creeping shrub, it is good for bees, moths and butterflies.
Common rosefinch
The common rosefinch is a rare visitor to the UK, usually passing through in autumn.
