Tegmina are pale bluish grey, hind marginal area is paler; hind wings are more grey and iridescent. Body white, scutellum and legs black. Abdomen covered with white feathery waxy excrescences.
The frons is longitudinally convex, genae anteriorly rotundate, neither frons nor genae produced in the middle. Ocelli distinct. Antennae: segments of the peduncle elongate, first extending considerably beyond the lateral margins of the genae, second about one-fifth longer than the first. Tegmina are very greatly decumbent, very ample, sensibly widened towards the apex, rotundate, with a single regular series of transverse nervures towards the apex; corium, etc. (except at the base) with numerous transverse nervures; many of the longitudinal nervures furcate.

Possible
About 20% of wildlife watchers report an Adelidoria glauca sighting in Sinharaja Forest Reserve on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 56th most-seen of the 117 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
April
In that month about 40% of wildlife watchers report an Adelidoria glauca in Sinharaja Forest Reserve on a given day, against under 5% in May to January, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Adelidoria glauca sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Sinharaja Forest Reserve, in our data
Sinharaja Forest Reserve is the only park on Wallace's Line with enough records to rate Adelidoria glauca sightings: about 20% of wildlife watchers there report one on a given day.
Same order: Hemiptera
The closest relatives of the Adelidoria glauca that you can see in Sinharaja Forest Reserve (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are Pyrops maculatus (about 50%), Platypleura westwoodi (about 20%) and Pibrocha egregia (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Adelidoria glauca is recorded against all the insects logged in Sinharaja Forest Reserve (8 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.
