Seasonal development
and life cycle—Roundheaded borer
Adult females of most species of roundheaded borers lay eggs
in bark crevices. The larvae bore beneath the bark and sometimes
into the wood on tree limbs, trunks, and main roots. During
the spring and summer the eucalyptus longhorned borer may
complete its life cycle in 3 to 4 months, but in the fall
and winter, it may require up to 9 months.
