Dragonflies and Damselflies

    GroupID-header-dragonflies-.jpg

    Introduction

    Dragonflies and damselflies are insects belonging to the order Odonata, which means 'toothed jaws'. Typically they have large eyes, two pairs of wings and are very mobile aerial hunters of other insects. They all breed in water though different species have preferences regarding still or running water, the size of water body, vegetation, etc. Their larvae live and develop in water and are ferocious predators of midge larvae and small invertebrates. Some species take up to 4 years to develop before climbing up waterside vegetation to metamorphosise into the beautiful adults we are familiar with.

    There are around 5,300 species worldwide but only about 120 in Europe and just 38 breed in Britain. The number of species in Leicestershire and Rutland changes over time but is around 26. A few species used to breed in our area but no longer do so. On the other hand, one or two species are expanding and have begun to breed here in recent years, such as the Small Red-eyed Damselfly (Erythromma najas). A few species are strong flyers and can migrate over large distances. See the checklist below for a full description of all the species found in Leicestershire and Rutland.

    Recording

    In VC55 the County Recorder for dragonflies and damselflies is Ian Merrill.

    As with all records, any submissions you make to NatureSpot will be automatically forwarded to both local and national recording schemes.

    ID Tips

    Most dragonflies and damselflies can be identified in the field, particularly if close-focus binoculars are used. Virtually all can be identified from a decent photograph, particular one that shows the colours and patterns on the abdominal segments.

    Keys

    There are sufficient visible differences between species that keys are generally not needed to identify species in this group. The field guides and resources described below provide excellent drawings and images that enable identification from careful observation. Nymphs are more similar and often require a good lens or microscope to observe the relevant features but can still generally be identified using a relevant guide.
