The fourth instar larva and pupa of Dasyhelea flavifrons Guérin-Méneville are redescribed, illustrated, and photomicrographed using binocular, phase-contrast, and scanning electron microscopy. The immatures were collected by using a siphon bottle in tree-holes and from water collected in dead snail shells in Salta Province, Argentina, transported to the laboratory and there bred to the emergence of the adults. Dasyhelea flavifrons is compared with all the American species of the grisea group, developing in diverse habitats including artificial containers. Details on larval habitats are given. These are the first records from Argentina and in gastrotelmata.
