|Lathrecista asiatica (Fabricius,
1798), the Asiatic Blood Tail, is a species of dragonfly in family Libellulidae.
It is the only species in its genus. The species is widespread, occurring
from India to Australia.
In males, the hindwing is 34 to 37
mm in length and the total body length ranges from 44 to 47 mm. The male
is easily recognised by its narrow, straight-sided abdomen, which is entirely
red, except for the last two segments which are black. The thorax is dark
brown with yellow stripes, especially on the sides. Older specimens may
develop pruinesence on the thorax. The young male is quite different to
that of the male. Its thorax isn't pruinosed allowing you to see the thoracic
markings clearly and their abdomen is more of an orange colour not blood
red. Also, the coloured wings tips are more obvious. This Species easily
confused with Potamarcha congener and Agrionoptera insignis.
The female has a brownish red abdomen,
which is thicker than that of the male. There is a yellow line running
over the thorax through the abdomen and gradually narrowed into a line
toward the tip. The female is much paler than the male (more like the young
male) and is easily mistaken for the extremely common Potomarcha congener.
The markings on the thorax, however, are different and the thorax is more
of an orange colour. It doesn't have large caudal appendages like P. congener
This species breeds in ponds, marshes,
swamp forest and shallow forest pools. It has been found in Kalimantan
on small pools in oil palm plantations where agrochemicals are heavily
used, so it is tolerant of disturbance and pollution. They are quite shy
and fly away with the slightest of movement.
asiatica pectoralis (Kaup in Brauer, 1867).
This species is very widespread,
occurring from India to Viet Nam and south to New Guinea and Australia.
It is assessed by IUCN Red List as Least Concern.
