Barnard (1932) described this species as follows: Imago: Paired intercalaries extending only to one space beyond MA1 or to CU1, or to anal angle. First cross-vein between R, and R, slightly proximal, or opposite, or slightly distal to cross-vein between R, and lR2. Body male 4.5-5.0 mm, female 5.0-5.5 mm; wing male 5 mm, female 5.5-6.0 mm; cerci 7-8 mm. Head pale ochre, medianly orange. Eyes black, ocelli white at tips. Prothorax brown, with orange transverse bar on anterior and posterior margins. Mesothorax dorsally castaneous brown, with pale yellow and darker brown markings, orange on humeral area, scutellum pale yellow, dark brown on either side; laterally and ventrally pale fulvous, with paler marks. Abdomen castaneous brown, with pale media-dorsal stripe, on each segment a comma-shaped mark, the tail of the comma pointing posteriorly and followed by a pale spot on either side of median line, faint on segment 9 and absent on segment 10; ventrally paler fulvous, uniform. Legs pale ochre. Cerci whitish, uniform. Wings clear, faintly milky in pterostigmal area, neuration pale brown. Nymph: Maxillary palp 3-jointed. Labial palp like that of B. bellus or Centroptilum excisum. Median cercus a little shorter than the others. Gills 6 pairs, none on the 1st segment, broadly oval. Up to 6 mm. Brown, with the abdominal pattern of imago. Cerci sepia, apical third of all three whitish. Gills transparent, tracheae dark.

Minnow mayfly nymphs are active swimmers or clingers (http://lifeinfreshwater.net/mayfly-nymphs-ephemeroptera/).

Herbivore - Folivore (leaf-eating)

The lifespan of adult mayflies ranges from several hours up to two days. Depends on the species and an ambient temperature plays a role too. The adult lifespan is so short, that there is no need for the insects to feed. Therefore the adult mayflies lack functional mouthparts and digestive tract. Nymphs are collectors/scrapers feeding on algae and detritus (http://lifeinfreshwater.net/mayfly-nymphs-ephemeroptera/).

Mayflies undergo incomplete metamorphosis. Their life cycle includes four stages – egg, nymph, subimago and adult (imago). Most species produce one or two generations per year (http://lifeinfreshwater.net/mayfly-nymphs-ephemeroptera/).
