2.4. Wax moth adults

The adult greater wax moth is approximately 15 mm long with a 31 mm average wingspan. The wings are grey in colour, though the hind third of the wing, normally hidden, is bronze coloured (Fig. 10). The wing venation patterns can be used as a diagnostic between greater and lesser wax moths (Ferguson, 1987; Fig. 11). Male greater wax moths are slightly smaller than females, lighter in colour, and have an indented, scalloped front wing margin in contrast to the females that have a straight front wing margin (Paddock, 1918). The female antennae are 10-20 % longer than those of the male (Paddock, 1918). Greater wax moths emerge as adults in early evening and find a protected place to expand and dry their wings. Greater wax moths do not feed as adults and the females live ~12 days while the males live ~21 days (Paddock, 1918).
