Immature Stages of Drosophilidae
Detailed information on immature
stages of Drosophilidae is being acquired.
However, Clausen (1940) noted that the eggs of Acletoxenus indica
Ald. are somewhat oblong, measuring 0.4 X 0.2 mm, and are covered with a
white waxy incrustation. They are
laid singly on the leaf surface adjacent to mature host larvae or pupae. The larva is at first translucent white in
color but later takes on a distinct greenish hue. It is very sluggish and never moves from the leaf on which the
egg was laid. A single host cluster
provides enough food to bring it to maturity. The larva in its later stages secretes an adhesive material
over the body which serves to attach various extraneous matter, including
host exuviae. Pupation occurs in situ
upon the leaf surface, and the developing fly can be readily seen through the
semitransparent puparial wall. Baerg (1920 observed that Drosophila inversa Wlk. larvae normally lie diagonally across the
dorsum of the host body, with the mandibles embedded in the 4th or 5th
abdominal segment. Please CLICK on picture to view details: References: Please refer to <biology.ref.htm>,
