“…Sexually selected weapons (hereafter: weapons) evolve via selection resulting from intrasexual competition over mates or resources important to mates. The majority of studies investigating the use of sexually selected weaponry have focused on males competing for access to females, which is common in insects (dung beetles, Onthophagus taurus , Moczek & Emlen, 2000 ; potter wasps, Synagris cornuta , Longair, 2004 ; giraffe weevils, Lasiorhynchus barbicornis , Painting & Holwell, 2013 , cave wētā, Pachyrhamma waitomoensis , Fea & Holwell, 2018 ), spiders (jumping spiders, Lyssomanes viridis , Tedore & Johnsen, 2012 ; sheetweb spiders, Cambridgea foliata , Walker & Holwell, 2018 ), crustaceans (shore crabs, Carcinus maenas , Sneddon et al, 1997 ; fiddler crabs, Uca spp., Swanson et al, 2013 ) and mammals (bighorn sheep, Ovis canadensis , Coltman et al, 2002 ), among other animals. However, females are also known to compete for mates with sex‐specific weaponry, such as occurs in jacanas (Berglund, 2013 ; Jenni & Collier, 1972 ).…”
