Basic Information About Sand Fly
In order to protect yourself from the infectious bites by the sand fly, it is essential to know that where it lives and how it spends its life. Below you will find key biological features related to the sand fly.
Appearance & Size
The sand fly falls under the family psychodid which has five more subfamilies. Among these psychodid subfamilies, only the sand fly is known for its sharp mouthparts that can pierce deep into the skin to suck the blood of the subject. They have long bodies, delicate anatomy and biologically known as the phlebotomine. Their outer appearance shows a hairy body with two large sized eyes in the head region and a pair of wings attached to the body. The overall measurement of the body is not more than 1.5 to 3.5 mm. The wings contrary to other flies are stand at an angle of 40 degrees in a rest position or while sucking the blood.
Behavior & Habit
The local climate of the née area directly affects the behavior of the sand flies. The fluctuations in temperature, humidity and the amount of rain have an influence on the lives of the sand flies. The lesser the temperature, the lesser will be the number of flies n the region. Some species are abundantly found all over the year in the tropical regions. The adult sand flies are not good fliers. They fly in a horizontal direction and stay close to the ground. The feeding options also vary from species to species, but their major hosts include the dogs, livestock’s, rodents and the human beings.
Distribution & Habitat
Geographically they are found in the tropical and sub-tropical regions. They are found between the 50°N and 40°S latitudes, but the population reduces in the case of New Zealand and the Pacific Islands. They are the dwellers of the hot and the humid environment. They find it comfortable to stay in the savanna and the semi-desert regions of the world. The eggs develop into larvae in the humid climate while the larvae then develop in a comparatively cooler and humid atmosphere.
Lifecycle & Damages
Adult sand flies don’t take much time to mate when they grow into an adult. The males use a special tracking chemical called the pheromones that help in finding out the females that are close to the resting locations or sitting on the vertebrates. A female after mating produces not more than 30 to 70 eggs during a single gonotrophic cycle. The eggs are kept safe in the tiny openings like the holes, cracks or burrows. As the eggs get proper environmental conditions like the humidity, they hatch into the larvae. In general, a female lays a single batch of eggs after having a single feast f blood.
Sand Fly Painful Bites
