Lyriothemis flava is a species of dragonfly in the family Libellulidae. It is found in Bangladesh, China, India, Japan, Myanmar, and Taiwan.

It is a medium-sized dragonfly with brown-capped greenish-yellow eyes. Its thorax is black on dorsum, yellow on sides. There is a thick black oblique stripe on the posterior half of mesepimeron and postero-lateral suture. Wings are transparent, tinted with amber-yellow at base.

With luck
About 10% of wildlife watchers report a Tricolour Bloodtail sighting in Taipei on a given day, based on 59 verified sightings from GBIF citizen-science data. It is the 190th most-seen of the 765 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April to August
In those months about 10% of wildlife watchers report a Tricolour Bloodtail in Taipei on a given day, against under 5% in September to March, the lowest months.
Only Taipei, in our data
Taipei is the only city on Wallace's Line with enough records to rate Tricolour Bloodtail sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Tricolour Bloodtail is recorded against all the insects logged in Taipei (59 verified sightings), 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.
