One of two ubiquitous red-bodied (♂) Sympetrum species found in the UK, the other being S. sanguineum (Ruddy Darter). S. striolatum tends to be a more orange-red and has a light stripe running longitudinally down each leg. It tends to be the last dragonfly, certainly the last darter, on the wing in the UK year.

- ♂ – contrasting brown and light yellowish panels on side of thorax
- mature ♂ – abdomen more orange in appearance than the very red S. sanguineum
