Immature Stages of Pteromalidae (Cleonyminae) Immature
stages of Cleonyminae were discussed in detail by Clausen (1940), as follows: The eggs of Cleonymidae had been
described for only the three species by 1940 (Clausen 1940). Those of S. paillotti
and S. sieboldi are elongate-oval or somewhat cylindrical in
outline, and that of C. colon (Fig. 80A) is narrowed at
both ends, with the anterior and drawn out into stalk-like form and at times
folded back upon the main body after deposition. In S. paillotti and C. colon, the chorion is clothed with minute spicules though
sparsely so in the last‑named species, whereas S. sieboldi
bears instead a fine reticulation on one side. The first‑instar larvae of
the family are hymenopteriform, with small sensory setae and the
integumentary setae may be uniformly distributed or in bands at the segmental
margins. The respiratory system is
equipped with spiracles on the mesothorax and first three abdominal segments.
The second‑ to fifth‑instar
larvae present no distinctive characters.
The sensory setae and integumentary spines are minute. Nine pairs of spiracles appear on the
fifth instar, these being situated on the second and third thoracic and the
first seven abdominal segments. Please CLICK on picture to view details: References: Please refer to <biology.ref.htm>, [Additional references may be
