Larvae tunnel into dead trunks and branches of southern beeches, rimu and Dracophyllum traversii.[1] This large weevil has a deep brown colour with two lighter bands near the side of its thorax. It has black legs with a spot of yellowish-brown hairs on each femur.[3] It has dense scales on its body, which can be hair-like. In female specimens the antennae are inserted halfway along the rostrum and nearer the front in males.[1] The larvae of Rhynchodes ursus are the host of New Zealand's largest parasitic wasp, Certonotus fractinervis. Female wasps use a long ovipositor to lay eggs inside the larvae whilst they develop inside trees.[2] References1. ^1 2 {{cite journal|last1=Lyal|first1=Chris|title=Cryptorhynchinae|journal=Fauna of New Zealand|date=1993|volume=29|url=https://www.landcareresearch.co.nz/__data/assets/pdf_file/0017/49004/FNZ29Lyal1993150_001.pdf|accessdate=25 February 2018}} {{Taxonbar|from=Q53996696}}2. ^1 {{cite web|title=Weevil (Elephant) Rhynchodes ursus|url=http://www.terrain.net.nz/friends-of-te-henui-group/local-insects/weevil-elephant-rhynchodes-ursus.html|website=T.E.R:R.A.I.N - Taranaki Educational Resource: Research, Analysis and Information Network|accessdate=25 February 2018}} 3. ^{{cite book|last1=Richardson|first1=John|last2=Gray|first2=John Edward|title=The zoology of the voyage of the H.M.S.
