Dayfly

A dayfly, belonging to the order Ephemeroptera, is a delicate, winged aquatic insect characterized by its short adult lifespan, typically lasting from a few hours to a few days. This ephemeral existence gives them their name, 'dayflies.' They undergo a complex metamorphosis, including a unique subimago stage. Adult dayflies are primarily focused on reproduction, laying eggs in freshwater environments. Their presence indicates good water quality, making them an important indicator species in aquatic ecosystems. They play a crucial role in the food chain, serving as a food source for fish, amphibians, and birds.
