Summary.1 1. At maturation, the first instar larva commences to feed upon the residual‐yolk‐mass contained in the anterior part of the egg, remaining within the chorion to do so. It takes three to five days to accomplish this. It sometimes eats a few particles of the walls or contents of the vessel before settling down to moult. 2 From seven to ten days after reaching maturity the young larva undergoes an ecdysis and then commences its boring operations in the wood.
