Sandflies are small, flying insects belonging to the family Psychodidae. They are typically found in warm, humid environments, often near beaches, marshes, and forests. Sandflies are most active during dusk and dawn, and their bites can cause itchy, red welts on the skin. These insects are known for their role as vectors for various diseases, including Leishmaniasis, which can affect both humans and animals. Sandflies are often mistaken for mosquitoes, but they are generally smaller and have a more robust body. Their presence can be a nuisance, especially in areas where they are abundant.
