Crocothemis servilia
Crocothemis servilia are seen near the ponds and streams.
They are very bright red in colour, and wings are transparent sometimes with a red patch on the base .
Males are seen more in number than females. Females come near to the water bodies at the time of mating Males are very active on good sunny days. The nymphs also are good feeders of mosquito larva.
Crocothemis servilia S hw 31-33 mm. Also with incomplete antenodal crossvein;
3 cell rows in cubital field as opposed to 2 (at some point) in R. rufa eyes
touching broadly (just touching in R. rufa). 9 light brown with venation and
structural details as in c?. Common in disturbed open habitats and agricultural
land, especially padi. Widespread in tropical and subtropical Eurasia.
Crocothemis servilia (Plate 2 la. Figs. 191-193) is a medium-sized (c? hw, 32-34
mm) red dragonfly easily confused with Orthetrum species, but distinguished by
the presence of an incomplete distal antenodal crossvein on the forewing. It is
widespread, normally found in artificial water bodies and cultivated land,
especially padi, up to at least 1000 m, but may be uncommon in parts of Borneo.
A very similar species is Rhodothemis rufa which is about the same size and also has an incomplete antenodal crossvein in the forewing. In Rhodothemis the eyes just meet at the top of the head (Fig. 28c) whereas in Crocothemis they are broadly touching (Fig. 2Sb). Moreover, the discoidal field in the forewing (that area extending to the wing margin from the triangle and bounded by two major veins—see Fig. 29b) has a minimum of three rows of cells in Crocothemis but at some point has only two rows in Rhodothemis.
If specimens of both species are available, other helpful distinctions are the pterostigma, which is relatively longer in Crocothemis, and the legs, which in Rhodothemis have much stronger spines.

The order of Odonata Dragonflies and Damselflies separated into three suborders, |
||
| Suborder #1 | Suborder #2 | Suborder #3 |
|
Anisoptera (dragonfly) |
Zygoptera (damselfly) |
Anisozygoptera () |
| 8 living families | 17 living families | |
|
|
|
| The order Odonata is pronounced in the English form "o do
NAY ta". This scientific name is derived from a Greek word, odon,
meaning " tooth," possibly referring to the teeth on the mandibles or
tusk-like shape of the insect's abdomen.
