Teneral
Definition:
(a.) Of, pertaining to, or designating, a condition assumed by the imago of certain Neuroptera, after exclusion from the pupa. In this state the insect is soft, and has not fully attained its mature coloring.
Example Sentences:

(3) There was little variation in the susceptibility of teneral male and female flies, young fed flies, and fed stud males with all the compounds tested (dieldrin, resmethrin, tetrachlorvinphos, bromophos, and propoxur) and increased tolerance in old fed pregnant flies occurred only with dieldrin and resmethrin.
(4) Teneral G. morsitans centralis were fed on a goat infected with T. vivax IL 1392 and dissected 1-2 h after feeding.
