Fighting between the males of many non-pollinating fig wasp species involves injuries and fatalities. Studies have shown that large males fight for mates, whereas conspecific small males tend to adopt nonfighting, sneaky behaviors. To analyze male morphs in two non-pollinating fig wasps (Philotrypesis taida Wong & Shiao, 2018 and Sycorycteridea taipeiensis Wong & Shiao, 2018) associated with the fig tree Ficus benguetensis, the head and mandible allometry and injuries were examined as well as the morphologies of their heads and mandibles. Male fig wasps of these two nonpollinating species can be divided into two morphological groups according to their head and mandible shapes. Approximately 88% of the Philotrypesis and 62% of the Sycorycteridea males were injured and no males belonging to largest morphs were decapitated. Moreover, nearly 31% of the Philotrypesis and 45% of the Sycorycteridea males left their natal figs. No difference in injury level or male exit rate between the male morphs was observed. This study reveals slight morphological and behavioral differences that may hint towards different mating strategies among morphs. © 2019 Pensoft Publishers. All rights reserved. |
