Life cycle In temperate climates, eggs laid on cypress the previous autumn hatch in spring. The countries where the relevant population could be native or where damage has not been reported, or where the date of introduction was so early that it is not known, are not included. The aphids feed on the bark of small twigs and branches in the inner and lower parts of the main canopy Ciesla, Retrieved 22 December There was no measurable effect of varying host-plant nutrition on the duration of the instars or overall survival.
