Although weapons are predicted to increase males' reproductive success, they are also expected to incur costs and may impair functional activities, including foraging. Using feeding assays, we tested whether the enlarged mandibles of Auckland tree w\u0113t\u0101 (\n                    <jats:italic>Hemideina thoracica<\/jats:italic>\n                    ) impact feeding activity (the total volume of biomass consumed, bite rate, and number of foraging visits) and foraging behaviour (time spent moving, feeding, or stationary). We predicted that increased head capsule size in male w\u0113t\u0101 would hinder their foraging efficacy. However, we found that w\u0113t\u0101 with longer heads fed at a faster rate and spent less time foraging than w\u0113t\u0101 with smaller heads, regardless of sex. Contrary to expectations that weapons impede functional activities, our results demonstrate that exaggerated traits can improve feeding performance and may offer benefits other than increased mating success.\n                  <\/jats:p>","DOI":"10.1098\/rsbl.2023.0207","type":"journal-article","created":{"date-parts":[[2023,11,15]],"date-time":"2023-11-15T03:05:11Z","timestamp":1700017511000},"update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Exaggerated mandibles are correlated with enhanced foraging efficacy in male Auckland tree w\u0113t\u0101"],"prefix":"10.1098","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2417-8968","authenticated-orcid":true,"given":"Bridgette","family":"Farnworth","sequence":"first","affiliation":[{"name":"Nelson Marlborough Institute of Technology, Nelson 7042, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samuel","family":"Purdie","sequence":"additional","affiliation":[{"name":"University of Otago, Dunedin 9054, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Priscilla M.","family":"Wehi","sequence":"additional","affiliation":[{"name":"University of Otago, Dunedin 9054, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0701-2648","authenticated-orcid":true,"given":"Christina J.","family":"Painting","sequence":"additional","affiliation":[{"name":"Te Aka M\u0101tuatua School of Science, University of Waikato, Hamilton 3240, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2023,11,15]]},"reference":[{"key":"e_1_3_8_2_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.ecolsys.39.110707.173502"},{"key":"e_1_3_8_3_2","doi-asserted-by":"publisher","DOI":"10.1098\/rspb.1987.0038"},{"key":"e_1_3_8_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5193(05)80088-8"},{"key":"e_1_3_8_5_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1558-5646.1991.tb02646.x"},{"key":"e_1_3_8_6_2","doi-asserted-by":"publisher","DOI":"10.1098\/rspb.2014.0876"},{"key":"e_1_3_8_7_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-185X.1995.tb01439.x"},{"key":"e_1_3_8_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/0022-5193(75)90111-3"},{"key":"e_1_3_8_9_2","doi-asserted-by":"publisher","DOI":"10.1002\/ar.1091620401"},{"key":"e_1_3_8_10_2","doi-asserted-by":"publisher","DOI":"10.2307\/1939292"},{"key":"e_1_3_8_11_2","doi-asserted-by":"publisher","DOI":"10.1163\/156853996X00530"},{"key":"e_1_3_8_12_2","doi-asserted-by":"publisher","DOI":"10.1111\/1365-2435.12294"},{"key":"e_1_3_8_13_2","doi-asserted-by":"publisher","DOI":"10.1242\/jeb.024547"},{"key":"e_1_3_8_14_2","doi-asserted-by":"publisher","DOI":"10.1093\/beheco\/ars069"},{"key":"e_1_3_8_15_2","doi-asserted-by":"publisher","DOI":"10.1098\/rspb.2013.0197"},{"key":"e_1_3_8_16_2","doi-asserted-by":"publisher","DOI":"10.1242\/jeb.163816"},{"key":"e_1_3_8_17_2","doi-asserted-by":"publisher","DOI":"10.1111\/1365-2435.13888"},{"key":"e_1_3_8_18_2","doi-asserted-by":"publisher","DOI":"10.1111\/evo.12018"},{"key":"e_1_3_8_19_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0082467"},{"key":"e_1_3_8_20_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1096-3642.1986.tb01186.x"},{"key":"e_1_3_8_21_2","doi-asserted-by":"publisher","DOI":"10.1093\/cz\/zoac101"},{"key":"e_1_3_8_22_2","doi-asserted-by":"publisher","DOI":"10.1079\/9780851994086.0000"},{"key":"e_1_3_8_23_2","doi-asserted-by":"publisher","DOI":"10.1002\/ece3.3763"},{"key":"e_1_3_8_24_2","doi-asserted-by":"publisher","DOI":"10.1111\/brv.12436"},{"key":"e_1_3_8_25_2","unstructured":"O'Brien B. 1984 Mandibular movements and their control in the weta Hemideina maori (Orthoptera: Ensifera: Stenopelmatidae).
