Copera vittata is a species of damselfly in the family Platycnemididae. It is native to Asia, where it is widely distributed from India to Indonesia. It is known commonly as the blue bush dart. There are several subspecies and it may represent a species complex.
It is a medium-sized damselfly with brown-capped yellow eyes with a narrow equatorial black band encircling them. Its thorax is black on dorsum with a narrow bluish-yellow humeral stripe, split in two and overlap each other. This stripe is followed by a broad black fascia, on the middle of the lateral side of the thorax, peppered with small pale yellow spots. The lateral sides beyond this is yellow, marked with an irregular black stripe on the anterior border of postero-lateral suture, and another one on the middle portion of metepimeron. Abdomen is black on dorsal half up to segment 8; paler on ventral half and with bluish-white basal annules. Segment 9 is black on basal half and bluish-white on apical half. Segment 10 is bluish-white.
Anal appendages are pale blue or creamy white. The superiors are as long as segment 10, conical, and tapered at apices. The inferiors nearly twice the length of... Wikipedia →

Possible
About 20% of wildlife watchers report a Blue Bush Dart sighting in Khao Yai National Park on a given day, based on 24 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 41st most-seen of the 221 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.
September
In that month about 40% of wildlife watchers report a Blue Bush Dart in Khao Yai National Park on a given day, against under 5% in June and November–January, the lowest months. That is one of Khao Yai National Park's wettest months, with about 330 mm of rain against 15 mm in December.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Blue Bush Dart sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 6 parks where we can rate Blue Bush Dart sightings, Khao Yai National Park has the highest daily chance: about 20%. Next come Danum Valley Conservation Area (Malaysia, about 10%) and Khao Sok National Park (Thailand, about 10%).
GBIF citizen-science records
It is estimated from how often the Blue Bush Dart is recorded against all the insects logged in Khao Yai National Park (24 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.
