Dark Jezebel

This guide uses Delias wilemani at the catalogue's species rank. Taiwan's National Museum of Natural Science instead uses Delias berinda wilemani. This is an alternative rank for the same named taxon, and it should not be counted twice in a species inventory. [1][3]

The specialist comparison with subnubila emphasizes a large yellow mark on the upper hindwing in space 2. A surface label is essential: an underside image cannot demonstrate an upper-wing diagnostic feature. Compare the spot's placement, neighbouring pale areas and the complete hindwing outline. [2]

Taiwan is the geographic context. The specialist page provides an attributed living photograph by Peelden, while the museum presents dorsal and ventral adult views. Neither resource is a modern island-wide occupancy map, and precise specimen localities remain valuable. [2][3]

The museum describes yellow ridged eggs, grouped larvae and dark pupae. Larvae have a dark head and a yellow-green, hairy body. The account concerns Taiwan's wilemani taxon under the berinda subspecies combination, and that scope should remain attached when the biology is cited. [3]

The museum lists Loranthus delavayi and two Taxillus species as larval hosts. These records belong to the Taiwanese taxon; they should not automatically become host claims for every berinda population. The exact plant determination matters when distinguishing the mistletoe from its supporting tree. [3]

Grouped larval feeding is a documented part of the museum account, whereas the living adult photograph supplies a different life-stage observation. Adult nectar visits and courtship need their own sources. A behaviour recorded for another Taiwanese pierid should not be imported into this account. [3]

Wilemani's rank disagreement matters because a life-history record may be indexed under berinda rather than wilemani. The record can still be used when its locality and taxon are explicit. Keeping the original combination makes the biological evidence recoverable across a change in classification.

The mistletoe records connect immature stages with local vegetation. Surveying those plants could reveal reproduction that adult photographs miss. Because the museum account uses an infraspecific name, the ecological relationship should be described at that Taiwanese scope before broader comparisons are attempted.

Dark Jezebel is the museum's English name. Its scientific combination differs from the catalogue's species treatment. A display should explain the alternative once, preserving both names in the reference record; the rank disagreement does not create a second newly discovered butterfly. [3]

This source set does not establish a current global threat category. Conservation records should be searched under both combinations and kept geographically explicit. A name change can fragment evidence across databases without representing any change in the living Taiwanese population.

Show the upper hindwing to explain the comparison with subnubila, then add the underside for a complete adult reading. The museum's two views are labelled for this purpose. Immature illustrations should retain the original Taiwanese combination and their source context.

Preserve the yellow mark in its correct upper-wing compartment. Use a determined Taiwanese adult as the reference and record its taxonomic combination. The guide can explain alternative rank without altering the observed butterfly or manufacturing an averaged berinda pattern.

Keep the frame in a stable, dry location. Retain both wilemani and berinda wilemani in the catalogue search terms. Original labels and the dated museum account allow the biological references to remain traceable if the preferred classification changes. [4]

What revision best explains the rank difference? Are the Taiwanese hosts used elsewhere within the broader berinda concept? Which adult and genital characters distinguish the taxon from subnubila and other regional relatives? Answering those questions separates identification from the decision about rank.

The Taiwan museum is the central biological source and makes its combination explicit, while the catalogue provides the species rank followed here. The specialist comparison supplies the upper-hindwing feature; its surface must stay attached to the diagnosis.
