Abstract: | Mate-seeking behaviours in males ofAnthidium septemspinosum are described. Mating occurred at the females' food plant patches, as in other congeneric species previously studied. Males
were behaviourally classified either as territorial or non-territorial. Territorial males were generally larger, and superior
in mating. Smaller males were forced to be non-territorial, adopting a different mating tactic of creeping into the territories
to intercept females. This compensated for their physical inferiority in mating competition. The adaptive significance of
this tactic is discussed. |
