Small blue
The small blue's name is a little misleading: it is our smallest butterfly, but only shows a dusting of blue on brown wings. It is scarce, occurring on chalk grassland, mostly in southern England.
Small copper
The small copper lives up to its name in both colour and size! Look out for it from April onwards in dry, sunny habitats like heathland, downland and woodland. It can be spotted in gardens, too.
Small heath
The small heath is the smallest of our brown butterflies and has a fluttering flight. It favours heathlands, as its name suggests, as well as other sunny habitats.
Small pearl-bordered fritillary
The small pearl-bordered fritillary is a pretty orange-and-brown butterfly of damp grassland, moorland, and open woodland. It gets its name from the row of 'pearls' on the underside of its hindwings.
Small skipper
Often found basking on tall grasses, or buzzing between stems, the small skipper is a small, orange butterfly. It prefers rough grassland, verges and woodland edges.
Small teasel
A prickly, tall plant, the Small teasel is closely related to the Common teasel, but has much smaller, more rounded flower heads. It prefers damp, open woodlands.
Small tortoiseshell
The pretty small tortoiseshell is a familiar garden visitor that can be seen feeding on flowers all year-round during warm spells. Overwintering adults may find resting spots in sheds, garages or even houses.
Small white
The small white is a common garden visitor. It is smaller than the similar large white, and has less black on its wingtips.
Small-leaved lime
A scarce tree of central and southern England, in particular, the Small-leaved Lime can be found in ancient woodland. It is has sweet-smelling flowers in summer and nut-like fruits in autumn.
Small-spotted catshark
Small-spotted catsharks used to be called lesser-spotted dogfish - which might be what you know them best as. It's the same shark, just a different name!
Smew
This small duck is an uncommon winter visitor to the UK, where they're usually found on lakes, reservoirs and gravel pits.
Smooth newt
You are likely to spot the smooth newt in your garden or local pond. It breeds in water in summer and spends the rest of the year in grassland and woodland, hibernating over winter.
