Scientific Name
In the scientific world, this tiny needle damselfly is known as Agriocnemis femina. In English, they are briefly called 'variable wisp' or 'pinhead wisp'.
Family and Genus
According to the classification of the animal kingdom, this insect belongs to the suborder Zygoptera of the order Odonata. It is mainly a well-known species of the genus Agriocnemis of the family Coenagrionidae.

Habitat and Distribution
They are mainly distributed from India through Southeast Asia to various island regions in the Pacific. They are naturally seen living in the canals, marshes, pond banks, small water bodies, ditches, or damp and wet grassy areas of our country. Especially stagnant quiet water and bushes around ponds are their most favorite places.

Food and Nutrition
Needle damselflies are mainly completely carnivorous or predatory insects. They consume nutrition by catching and eating very small insects, mosquitoes, flies, and harmful tiny bugs floating in the air or off leaves around water bodies.

Shape and Lifestyle
In size, they are much smaller and lighter compared to ordinary dragonflies. Their body looks just like a thin needle. A light whitish powder or wax-like coating can be seen on the body of mature or adult male damselflies, and their tail end is quite dark in color. Their wings are transparent. Instead of flying very high, they love to fly slightly above grass and foliage near quiet water.

Benefits
They are a very useful insect for agriculture and the environment. They help control harmful pests naturally by preventing the breeding of mosquitoes around water bodies and hunting small insects harmful to crops. Their role in maintaining the balance of our ecosystem is quite commendable.

Harmful Effects
They have not the slightest harm for humans, crops, or fruit gardens. They do not bite humans and do not damage or harm leaves of any trees in the garden. Therefore, their presence in the garden is good for the environment.
