Source-derived summary

Jalmenus icilius, the Icilius blue or amethyst hairstreak, is a butterfly of the family Lycaenidae. It is found in all mainland states of Australia, throughout much of the subtropical areas of the inland, from the Selwyn Range and from Carnarvon to Kalgoorlie. It is generally common except in the south-eastern end of its range in central and western Victoria, where it is now very scarce.

The wingspan is about 30 mm.

The larvae feed on a wide range of plants, including Cassia artemisioides, Cassia nemophila, Daviesia benthamii, and the Acacia species: A. acuminata, A. anceps, A. aneura, A. dealbata, A. deanei, A. harpophylla, A. mearnsii, A. parramattensis, A. pendula, A. pycnantha, A. rubida, A. saligna and A. victoriae.

The caterpillars are attended by the ant species Iridomyrmex rufoniger.

Editorial summary

“Jalmenus icilius” enters the record as species of insect. Crown Archives preserves that source wording while asking what Jalmenus, icilius and species can confirm, complicate or overturn.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 128-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 strongest next move is a source search built around Jalmenus, icilius and species.
Editorial analysis

Why this record matters

“Jalmenus icilius” is worth following because a concise public description often conceals a longer documentary argument. Here, Jalmenus, icilius and species provides the most credible route into that argument.

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 Apr 27, 2024. The linked authority identifier is Q769256. 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 lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. 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.
