Mayflies

Definition

Aquatic insects in the order Ephemeroptera, characterized by short lifespans, transparent wings, and an aquatic nymph stage called a naiad.

Etymology

Derived from the genus name 'Ephemera', which comes from the Greek word 'ephemeros' meaning 'short-lived', due to their brief adult life span.

Example

Mayflies are often found near freshwater habitats where their nymphs develop and metamorphose into flying adults.
