* Adults are good fliers and easily disperse. Adults chew into the grain kernels from the
outside and also to lay eggs. Females can lay 300 to 400 eggs typically one per cavity.
Larvae develop through several stages (instars) inside the grain kernels and also pupate
inside the kernel. They may complete a generation in a month in warm conditions. Adults
often live for 7 to 8 months and some records are over 2 years.
