Development
Eggs are laid singly under old leaves of the host plant and are green or grey-blue. None of the three species is restricted to a single family of host plant; hosts are typically in the families Solanaceae, Verbenaceae, Oleaceae, Bignoniaceae, and others. The larvae are stout, reaching 120–130 mm, with a prominent tail horn. All three species have three larval color forms: typically, green, brown, and yellow. Larvae do not move much, and will click their mandibles or even bite if threatened. When mature, they burrow underground and excavate a small chamber where they pupate.

Famous quotes containing the word development:
“The man, or the boy, in his development is psychologically deterred from incorporating serving characteristics by an easily observable fact: there are already people around who are clearly meant to serve and they are girls and women. To perform the activities these people are doing is to risk being, and being thought of, and thinking of oneself, as a woman. This has been made a terrifying prospect and has been made to constitute a major threat to masculine identity.”
—Jean Baker Miller (20th century)
“John B. Watson, the most influential child-rearing expert [of the 1920s], warned that doting mothers could retard the development of children,... Demonstrations of affection were therefore limited. “If you must, kiss them once on the forehead when they say goodnight. Shake hands with them in the morning.””
—Sylvia Ann Hewitt (20th century)
“There are two things which cannot be attacked in front: ignorance and narrow-mindedness. They can only be shaken by the simple development of the contrary qualities. They will not bear discussion.”
—John Emerich Edward Dalberg, 1st Baron Acton (1834–1902)
