Choice tests showed that tracks left by coccinellid larvae have generally little effect on oviposition site selection by chrysopid females.Fresh tracks of first instar larvae of enforcer wave to open the coccinellid species Coccinella septempunctata, Cycloneda limbifer, Leis dimidiata and Semiadalia undecimnotata, did not deter females of the chrysopid Chrysopa oculata from laying eggs.Females of Chrysopa perla avoided focus st g25-660 ovipositing only on substrates with tracks of L.dimidiata larvae.
