By zooming in I was able to see that the cluster of mites at 11 o&#8217;clock are phoretic deutonymphal Astigmata. There&#8217;s not enough detail to say what family, but the most likely are Acaridae or Histiostomatidae. The two mites on the substrate in photo 3 (plus two that you can see on the beetle itself) look like nymphal Mesostigmata. What they are doing on the beetle is a good question! They are not the typical uropodine mesostigs that would use the adult beetle as a phoretic host; rather, they look more gracile, possibly Parasitidae or Macrochelidae (which also are frequently phoretic on insects).\u00a0 <\/span><span style=\"font-family: georgia,serif; font-size: small;\">Sorry I can&#8217;t identify them any more finely than Astigmata and Mesostigmata based on the photos.<\/span><\/p>\n<p>&nbsp;<\/p>\n<div>\n<p>&nbsp;<\/p>\n<p style=\"text-align: center;\"><img decoding=\"async\" title=\"beetlegrub1.JPG\" src=\"https:\/\/www.vicnhs.bc.ca\/wp-content\/uploads\/2017\/01\/beetlegrub1.jpg\" width=\"599.2\" height=\"449.40000000000003\" name=\"\" \/><\/p>\n<div style=\"text-align: center;\">Probably\u00a0 <em>Polyphylla crinita <\/em>(Col.: Scarabaeidae)\u00a0\u00a0 Ian Cruickshank<\/div>\n<p style=\"text-align: center;\"><img decoding=\"async\" title=\"beetlegrub2.JPG\" src=\"https:\/\/www.vicnhs.bc.ca\/wp-content\/uploads\/2017\/01\/beetlegrub2.jpg\" width=\"599.2\" height=\"449.40000000000003\" name=\"\" \/><\/p>\n<div style=\"text-align: center;\">\n<p><img decoding=\"async\" class=\"\" style=\"margin: 5px;\" src=\"file:\/\/\/F:\/DOCUME%7E1\/tatum\/LOCALS%7E1\/Temp\/msohtml1\/01\/clip_image004.jpg\" alt=\"\" \/>Probably\u00a0 <em>Polyphylla crinita <\/em>(Col.: Scarabaeidae)\u00a0\u00a0 Ian Cruickshank<\/p>\n<\/div>\n<p style=\"text-align: center;\"><img decoding=\"async\" title=\"beetlegrub3.JPG\" src=\"https:\/\/www.vicnhs.bc.ca\/wp-content\/uploads\/2017\/01\/beetlegrub3.jpg\" width=\"599.2\" height=\"449.40000000000003\" name=\"\" \/><\/p>\n<div style=\"text-align: center;\"><img decoding=\"async\" class=\"\" style=\"margin: 5px;\" src=\"file:\/\/\/F:\/DOCUME%7E1\/tatum\/LOCALS%7E1\/Temp\/msohtml1\/01\/clip_image006.jpg\" alt=\"\" \/>Probably\u00a0 <em>Polyphylla crinita <\/em>(Col.: Scarabaeidae)\u00a0\u00a0 Ian Cruickshank<\/div>\n<p>&nbsp;<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>2017 January 21 \u00a0 \u00a0\u00a0 Ian Cruickshank sends photographs of a beetle grub from Sidney Island.\u00a0 This would appear to be the same species as the one photographed by Morgan Davies from the same island, posted on this site for December 1.\u00a0 The beetle is in the Superfamily Scarabaeoidea.\u00a0 Ian\u2019s photograph shows that it is [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[8],"tags":[],"class_list":["post-3594","post","type-post","status-publish","format-standard","hentry","category-invertebrate-alert"],"_links":{"self":[{"href":"https:\/\/www.vicnhs.bc.ca\/index.php?rest_route=\/wp\/v2\/posts\/3594","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.vicnhs.bc.ca\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.vicnhs.bc.ca\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.vicnhs.bc.ca\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.vicnhs.bc.ca\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=3594"}],"version-history":[{"count":3,"href":"https:\/\/www.vicnhs.bc.ca\/index.php?rest_route=\/wp\/v2\/posts\/3594\/revisions"}],"predecessor-version":[{"id":3647,"href":"https:\/\/www.vicnhs.bc.ca\/index.php?rest_route=\/wp\/v2\/posts\/3594\/revisions\/3647"}],"wp:attachment":[{"href":"https:\/\/www.vicnhs.bc.ca\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=3594"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.vicnhs.bc.ca\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=3594"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.vicnhs.bc.ca\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=3594"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
