Underside: brown. Forewing: transversely traversed by three pairs of white strigae, the innermost pair slightly curved, from subcostal vein to vein 1 across the middle of the cell; the inner striga of the medial pair complete, crosses on the inner side of the discocellulars from subcostal vein to vein 1, the outer striga beyond the discocellulars from vein 7 to vein 1, interrupted in interspace 5; the outer pair of strigae are discal and cross -from vein 7 to vein 3, the inner striga of the pair impinging at vein 3 on the outer striga of the medial pair...

With luck
About 10% of wildlife watchers report a Transparent 6-Line Blue sighting in Taroko National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 148th most-seen of the 447 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Transparent 6-Line Blue is recorded against all the insects logged in Taroko National Park (14 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
