Slim scarlet-darter description

KingdomAnimalia
PhylumArthropoda
ClassInsecta
OrderOdonata
FamilyLibellulidae
GenusCrocothemis (1)

The slim scarlet-darter (Crocothemis sanguinolenta) is a medium-sized dragonfly with dazzling scarlet colouration and a long, slender body (2). Its eyes are large and positioned close together on top of the head (3). The slim scarlet-darter has two pairs of membranous wings with visible veins running through them and characteristic dark spots near the tip of the wing (4).

The slim scarlet-darter often has a small patch of yellow at the base of the wings, and this feature is variable in size between populations, with some scientists recognising two subspecies: Crocothemis sanguinolentaarabica and Crocothemis sanguinolenta sanguinolenta (5). Like other dragonflies, the slim scarlet-darter holds its wings flat and at 90 degrees to the body (3).

Also known as
little scarlet, small scarlet.

Slim scarlet-darter biology

There is little specific information available on the biology of the slim scarlet-darter but its life history and behaviour are likely to be similar to those of other dragonflies and damselflies.

Adult dragonflies typically hold a small territory, which is vigorously defended during breeding. Aggression can be increased when there is an imbalance between the numbers of each sex (6). During mating, the male dragonfly holds the female by the head with a pair of claspers on the end of the abdomen. The male may make an attempt to remove any sperm stored by the female from previous mates, and will often try to guard the female from other males during egg laying, to ensure that the eggs are fertilised by his sperm (6).

A dragonfly generally lays its eggs near or in water, and the eggs hatch into aquatic larvae, known as nymphs. Dragonfly nymphs go through several moults before the final moult into the adult form. When the nymph is ready to emerge as an adult, it finds a safe spot hidden from potential predators, as it is very vulnerable at this stage. Once the adult has emerged, it pumps fluid into the veins in the wings to expand them ready for flight. The larval stage of a dragonfly may last for many months, whereas the adult may only live for a matter of weeks (6).

Both adult and larval dragonflies are opportunistic predators, feeding on a variety of prey.

Glossary

Fertilisation
The fusion of gametes (male and female reproductive cells) to produce an embryo, which grows into a new individual.
Larval
Of the stage in an animal’s lifecycle after it hatches from the egg. Larvae are typically very different in appearance to adults; they are able to feed and move around but usually are unable to reproduce.
Moult
In insects, a stage of growth whereby the hard outer layer of the body (the exoskeleton) is shed and the body becomes larger.
Nymph
Stage of insect development, similar in appearance to the adult but sexually immature and without wings. The adult form is reached via a series of moults, and the wings develop externally as the nymph grows.
Subspecies
A population usually restricted to a geographical area that differs from other populations of the same species, but not to the extent of being classified as a separate species.
Territory
An area occupied and defended by an animal, a pair of animals or a group.
