They can be black, brown or mottled yellow. Larvae are yellowish with a brown head and forked tail, and they are about 5 mm long when fully grown. Carpophilus adult Life cycle Driedfruit beetles attack a wide variety of hosts including stone fruit, persimmons, fallen citrus, apples, and figs. They do not breed in fruit on the tree. Adults lay eggs in rotting or damaged fruit on the orchard floor.
Mature larvae emerge from the fruit and pupate in the ground.
Adults emerge from the pupae and attack fruit in late spring and summer. If no hosts are available they overwinter in cracks in the tree, under bark or in mummified fruit. It takes about a month in summer to develop from egg to adult so there are many generations per year. Driedfruit beetles are strong fliers and can travel several kilometres in search of hosts. Summer rainfall and rotting of fruit provides the best conditions for beetle breeding.
