The eggs hatch after some three weeks, each producing a 1 mm long, creamy white, C-shaped larva.
Their eggs, which they like to deposit in rich soil, hatch into tiny white larvae.
The eggs hatch after two to four weeks and the legless white larvae, which are fed by the workers, pupate about a month later.
In about three days the tiny eggs hatch, releasing the small white or yellow-green larvae.
The white, brown-headed larva, when fully grown, is 3.2 to 5.0 mm long.
The queen had been laying eggs recently, as white grublike larvae could be seen in the cells of honeycomb.
Like those of other stag beetles, the white, C-shaped larvae feeds on wood.
Several, or sometimes one white larva are found in each gall, feeding upon the plant tissues.
These hatch into tiny smooth white larvae with four pairs of anal gills.
The grey and white larva feeds on poplar and aspen.
