(p. 194
et seq.)
Stout-bodied flies clothed in soft hair;
hypopleural bristles present; postscutellum
well developed; females with an extensile
oviscapt. Larvae are internal parasites of mam-
mals and some are of considerable economic
importance.
EXAMPLES:
Hypoderma
spp.
Minute to small flies with a bare arista, brightly
coloured eyes, a very large ocellar triangle
(Fig.

and reduced wing venation (no anal cell)
(Fig. 109).
Some species have predacious larvae
(including
Chloropisca glabra
which feeds on
root aphids) but most are phytophagous; larvae
elongate, with prominent anterior and posterior
(warble flies),
Oestrus ovis
(sheep nostril fly).
