Source-derived summary

The blue-spotted hawker (Adversaeschna brevistyla) is the only known species of dragonfly of the genus Adversaeschna in the family Aeshnidae. They are also known as the Lancer Dragonfly. Their scientific name was formerly Aeschna brevistyla but was relatively recently changed to be Adversaeschna brevistyla

Appearance

The blue-spotted hawker is a large dragonfly with a pair of pale stripes on either side of the thorax. At the base of the thorax, they have two symmetrical bright-blue stripes. The fore-edges of the wings are a pale orange with the color ending at the pterostigma, which is a reddish-brown. Mature males have blue eyes whilst females have brown eyes.

Distribution and Habitat

The blue-spotted hawker is widespread across Australia, New Zealand and some Pacific Islands.

It may be found near ponds and marshes as well as vegetation far from water. It prefers still water but may also be found along calm streams.

Conservation Status

As of 2019, they were marked as least concern in their risk of being threatened.

Editorial summary

Begin with the source’s own compact description: “Blue-spotted hawker” is species of insect. The dossier treats that line as a proposition to test through Blue-spotted, hawker and species, not as a finished interpretation.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current lead gives the account dated anchors—2019—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Blue-spotted, hawker and species is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “species of insect” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 10, 2026. The linked authority identifier is Q1375679. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2019.

Critical limits

A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
