The female lays egg underside of the leaf and one at a time. After hatching, caterpillar bores into the leaf. As leaves of the bryophyllum are thick enough to host it, caterpillar can remain inside the leaf till pupation.  When eatable part of the leaf is finished, caterpillar shift to some other. Caterpillar of these species is easiest find, although hidden inside the leaf. When it bores in between the two epidermal layers of leaf, it fills it with its excreta. Searching for the black pouches filled with excreta may lead tot the caterpillar. Caterpillar is flat as it leaves inside the leaf. Its light yellow in color with white hairs on the body.Caterpillar comes out of the leaf at tht time of pupation. Normally pupa is approx 10 mm long and is formed on or under the leaf. Key characteristic is the numerous black dots  all over the pupa. In field, UN wing photograph of red pierrot while nectoring can easily be shot.
