Abstract
Morphological features of the eggs ofEuxoa campestris,E.declarata, andE.rockburnei, the “declaratagroup”, were diagnostic for the species; the esterase zymograms of the eggs ofcampestrisanddeclaratasupport the morphological findings. Chorionic features and the esterase zymograms of a hybrid resembled those of the female parent.
