1934Folsom & Wardle Entomol. (ed. 4) iii. 169 As a rare abnormality a holometabolous larva may possess two pairs of true external wing-pads... The phenomenon is termed prothetely. 1940R. Goldschmidt Material Basis of Evolution iv. 283 The actual working of this timing mechanism can be inferred from cases of so-called prothetely, where a single larval organ, e.g. wings or antennae, metamorphoses alone.

Entomol. iv. 83 (caption) Prothetelic larva of Tenebrio molitor.. showing rudiments of wings. Ibid., Prothetely. Quite often when bred artificially, but more rarely in nature, insect larvae may have rudiments of wings, which have matured at a greater rate than the rest of the body. 1978Nature 23 Mar. 350/2 They..obtained morphogenetic effects (precocious-prothetelic adults after administration to young instars) only in Heteroptera. |
