One of the most enigmatic insect hormones, juvenile hormone (JH), plays a critical role in regulating insect development, metamorphosis, and reproduction. JH is popularly known as the “status quo” hormone because application of JH or a JH mimic to a last instar nymph prevents the metamorphic molt, causing an additional immature stage in many insects. On the other hand, early elimination of the hormone induces premature metamorphosis, which produces miniature adults. This infographic visually summarizes these phenotypes associated with abnormal JH signaling in both hemimetabolous and holometabolous insects.
