Dragonflies are one of the oldest insects that ever roamed the earth. They have large, strong jaws and basket-like gantry legs used to catch their prey.

According to National Geographic, there are around 7,000 species of dragonflies today with their closely related damselflies, forming the group Odonata. This means ‘toothed ones,’ which are considered to be ancient.

Identifying a dragonfly isn’t challenging when landed at a close range. However, this gets tricky once the dragonfly starts flying rashly.
Nonetheless, most of these insects land sometimes. So, you can try to get a good look and identify them when that happens. It will also be helpful to know the basic anatomy of a dragonfly in identifying them. They have a head, thorax, and abdomen.

The shape of their abdomen helps in identifying the sexes of these dragonflies.
- Males have a distinct bulge under their secondary genitalia.
- Females don’t have protruding structures and generally have a broader and enlarged abdomen to carry many eggs.
Types of Dragonfly
There are two types of dragonflies when it comes to foraging style—the fliers and the perchers.
Fliers: They fly around to catch their prey while perchers rest on seats, observing their target, the predators, and their species members.
