Source-derived summary

Libellula depressa, the broad-bodied chaser is one of the most common dragonflies in Europe and central Asia. It is very distinctive with a very broad flattened abdomen, four wing patches and, in the male, the abdomen becomes pruinose blue.

Identification

This insect is around 39–48 mm in length, with both the male and the female having a broad, flattened abdomen which is brown with yellow patches down the sides. In the male, the abdomen develops a blue pruinosity that covers the brown colour. Both fore and hind wings have a dark patch at the base. Both the male and female have broad antehumeral stripes. The average wingspan is approximately 70 mm. L. depressa is very distinctive and is not easily confused with any other dragonflies in the region.

Distribution and habitat

L. depressa is found in central and southern Europe, central Asia and the Middle East. Its range extends northwards throughout England and Wales and into southern Scotland, southern Sweden and southern Finland.

Editorial summary

The public source identifies “Libellula depressa” as species of insect. This brief keeps that definition visible, then builds a research path around Libellula, depressa and species.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 163-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Libellula, depressa and species providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Libellula depressa”, the useful work is to connect “species of insect” to the records capable of establishing context and consequence.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jun 23, 2026. The linked authority identifier is Q302485. None of the 0 selected statements returned an explicit reference.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
