  4. 4. Order: Ephemeroptera • Mayflies (order Ephemeroptera) represent the oldest order of the existing winged insects. • They are unique among the insects in having two winged adult stages, the subimago and imago.• As adults they generally live from 1 to 2 hrs to a few days, and mayflies spend most of their life in the aquatic environment, either as eggs or larvae.
  5. 5. Larvae• 12 – 45 molts• Chewing mouthparts always functional• Gills absent in instars early instars.• Variable median caudal filament (i.e., 2-3 “tails”)
  6. 6. Imago• Wings shiny, iridescent, with hind margins usually bare.• Short setaceous antennae.• Two-pair of triangular, membranous wings with many veins. The fore-wings are larger than hind- wings.• The wings are held vertically at rest.• Body glossy, upwardly concave trunk.• Forelegs much elongated, esp. males.• Caudal filaments usually not hairy, typically longer, brittle, straight.• Compound eyes prominent, glossy.• Mandibles stunted, non-functional.
