Sperm investment in relation to weapon size in a male trimorphic insect?

In the harem polygynous Wellington tree weta (Hemideina crassidens), early maturation at the eighth instar by males is associated with smaller mandibular weaponry. Because these males, compared with larger males (i.e., matured at 10th instar), are less successful at holding harems, they appear to have decreased mating success. Therefore, smaller males may acquire mates using tactics different than those of males with larger weaponry. A source of empirical support for this hypothesis is to show...[Show more]
