Here, we describe similar controlled aerial behaviours for large arboreal spiders in the genus\n            <jats:italic>Selenops<\/jats:italic>\n            (Selenopidae). We dropped 59 such spiders from either canopy platforms or tree crowns in Panama and Peru; the majority (93%) directed their aerial trajectories towards and then landed upon nearby tree trunks. Following initial dorsoventral righting when necessary, falling spiders oriented themselves and then translated head-first towards targets; directional changes were correlated with bilaterally asymmetric motions of the anterolaterally extended forelegs. Aerial performance (i.e. the glide index) decreased with increasing body mass and wing loading, but not with projected surface area of the spider. Along with the occurrence of directed aerial descent in ants, jumping bristletails, and other wingless hexapods, this discovery of targeted gliding in selenopid spiders further indicates strong selective pressures against uncontrolled falls into the understory for arboreal taxa.\n          <\/jats:p>","DOI":"10.1098\/rsif.2015.0534","type":"journal-article","created":{"date-parts":[[2015,8,26]],"date-time":"2015-08-26T17:53:43Z","timestamp":1440611623000},"page":"20150534","update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":32,"title":["Arachnid aloft: directed aerial descent in neotropical canopy spiders"],"prefix":"10.1098","volume":"12","author":[{"given":"Stephen P.","family":"Yanoviak","sequence":"first","affiliation":[{"name":"Department of Biology, University of Louisville, 139 Life Sciences Building, Louisville, KY 40292, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yonatan","family":"Munk","sequence":"additional","affiliation":[{"name":"Department of Integrative Biology, University of California, Berkeley, CA 94720, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert","family":"Dudley","sequence":"additional","affiliation":[{"name":"Department of Integrative Biology, University of California, Berkeley, CA 94720, USA"},{"name":"Smithsonian Tropical Research Institute, Balboa, Republic of Panama"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"175","published-online":{"date-parts":[[2015,9,6]]},"reference":[{"key":"e_1_3_5_2_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1226727"},{"key":"e_1_3_5_3_2","doi-asserted-by":"publisher","DOI":"10.1093\/icb\/icr006"},{"key":"e_1_3_5_4_2","doi-asserted-by":"publisher","DOI":"10.1242\/jeb.101600"},{"key":"e_1_3_5_5_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature03254"},{"key":"e_1_3_5_6_2","doi-asserted-by":"publisher","DOI":"10.1098\/rsbl.2009.0029"},{"key":"e_1_3_5_7_2","doi-asserted-by":"publisher","DOI":"10.1093\/icb\/icr002"},{"key":"e_1_3_5_8_2","doi-asserted-by":"publisher","DOI":"10.1242\/jeb.02170"},{"key":"e_1_3_5_9_2","doi-asserted-by":"publisher","DOI":"10.1098\/rspb.2010.0170"},{"key":"e_1_3_5_10_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.ecolsys.37.091305.110014"},{"key":"e_1_3_5_11_2","doi-asserted-by":"publisher","DOI":"10.1080\/00222930802354183"},{"key":"e_1_3_5_12_2","doi-asserted-by":"publisher","DOI":"10.3897\/zookeys.105.724"},{"key":"e_1_3_5_13_2","volume-title":"The ecology of a tropical forest","author":"Leigh EG","year":"1996","edition":"2"},{"key":"e_1_3_5_14_2","volume-title":"Fl\u00f3rula de las reservas biol\u00f3gicas de Iquitos, Per\u00fa","author":"V\u00e1squez Mart\u00ednez R","year":"1997"},{"key":"e_1_3_5_15_2","first-page":"165","article-title":"Microclimatic characteristics of a primary tropical Amazonian rain forest, ACEER, Iquitos, Peru","volume":"21","author":"Madigosky SR","year":"2000","journal-title":"Selbyana"},{"key":"e_1_3_5_16_2","doi-asserted-by":"publisher","DOI":"10.1076\/snfe.33.2.124.2153"},{"key":"e_1_3_5_17_2","first-page":"1","article-title":"A study of the spider family Selenopidae in North America, Central America, and the West Indies","volume":"1619","author":"Muma MA","year":"1953","journal-title":"Am.
