Baetidae is a widespread and abundant family that occurs in a variety of streams, and also in permanent and temporary ponds or littoral zones of lakes. Lotic species are sometimes univoltine, but more frequently bivoltine; most species overwinter as diapausing eggs.

Baetids breed in a wide range of waters from lakes and streams to ditches and even water butts. The nymphs are strong swimmers and feed mainly on algae.

The larvae of this family are usually found in lotic-erosional or lotic-depositional habitats. They tend to be clingers and strong swimmers due to their streamlined, minnow-like body shape. They feed by collecting and gathering food, or by scraping algae …

Baetidae is an abundant and diverse family of small to medium-sized mayflies found in freshwater habitats around the world. Members are known for their streamlined bodies and quick, darting flight patterns.

Baetid nymphs live in almost all types of freshwater habitats. Swimmers/clingers. Mature nymphs can grow up to sizes around 12 mm (not including antennae and caudal filaments). Mayflies undergo incomplete metamorphosis. Their life cycle includes four stages – egg, nymph, subimago and adult (imago).

Information on the biology of Baetidae can be found on page 56. Baetidae look similar to Siphlonuridae, although Baetidae have a notched labrum and antennae at least 2x the width of the head.

This study considered evidence of the phylogenetic structure of three species of Baetidae corresponding to two different habitat requirements. Results indicate that habitat-restricted Demoreptus species have greater maternal genetic structure than widespread A.sudafricanum, showing notable genetic differentiation associated with geographic ...

Baetidae is a family of mayflies with about 900 described species distributed worldwide. These are among the smallest of mayflies, adults rarely exceeding 10 mm in length excluding the two long slender tails and sometimes much smaller, and members of the family are often referred to as small mayflies or small minnow mayflies.

The new species of Baetidae are deposited in Zoological Survey of India (ZSI), southern regional centre, Chennai and other species are deposited in Museum of Zoology, Thiagarajar College (MZTC), Madurai, Tamil Nadu, India, as reference collections of southern Western Ghats.
