Larva when attacks the bud of lesser than 10 days old, shedding of bud occurs and larva dies. But with older bud, larva can complete development. Larva in flower bud spins webbing that prevents proper flower opening leading to rosetted-bloom. Ten to twenty days old bolls are attacked from under bracteoles. Larvae feed on the developing seeds. While in younger bolls entire content may be destroyed, in older bolls development could be completed on three to four seeds. Interloculi movement is also seen. Several larvae can infest a single boll.
