Lichtensia viburni: female

adult, but not yet ovigerous female (from Malumphy, 2015a)

Lichtensia viburni: ovisac on Hedera helix

Hedera helix, ovisac (from Jansen, 2009a).


The eggs that have been deposited in the autumn soon hatch. After a first mobile stage the larvae settle at the underside of the leaves and pass the winter as 2nd or 3rd instar larvae. In the spring the female 3rd instar larvae migrate to young shoots, where they molt for the last time. The male larvae do not migrate, but form a narrow-oval shield, consisting of 9 wax platelets. Under this shield the last moult takes place and the adult, two-winged males fly out to fertilise the females. The fertilised females remigrate to the leaves. Their bodies quickly swell as their eggs start to develop. Around their bodies large quantities of white wax-wol are formed into an ovisac, into which the eggs are deposited. The female then dies; her desiccated body remains in the ovisac that is almost completely filled with eggs and is ± 7 mm long (Quaglia & Raspi).
