Steroid hormone signaling during development has a latent effect on adult male sexual behavior in the butterfly Bicyclus anynana
It is well established that steroid hormones regulate sexual behavior in vertebrates via organizational and activational effects. However, whether the organizational/activational paradigm applies more broadly to the sexual behavior of other animals such as insects is not well established. Here we de...

It is well established that steroid hormones regulate sexual behavior in vertebrates via organizational and activational effects.
