Ynghylch

The Large red damselfly is a medium-sized damselfly that lives around the edges of ponds, lakes, ditches and canals, and can also be found away from breeding sites in grassland and woodland. The earliest damselfly to emerge in the UK, it is on the wing from the end of April through to August. It is a regular visitor to gardens.

Sut i'w hadnabod

Male Large red damselflies are bright red with a black thorax and black bands towards the end of the body. The amount of red and black on the females' abdomens varies, with some forms appearing almost entirely black. The similar Small red damselfly is a much rarer species that is only found on heathlands in the south of England and West Wales. It is smaller, more delicate and has less red than its larger relative.
