Multi-female colonies in WW were present in early
spring and were 86% solitary female by by late
spring
Another observation site, Yamba, had multi-female
colonies during the winter, but were completely
solitary by mid-spring
This is species is bivoltine (produces 2 generations
each year). This was determined by the fact that
newly emerged females in mid-summer were
mated and laid eggs in WW
The most significant difference between the two
species is that the X. bombylans are bivoltine and
the X. aeratus are univoltine (produces one brood
per year)
