In the usual keys (e.g. Belshaw, 1993) <em>Carcelia <\/em>and <em>Senometopia <\/em>are brought out using the relative height of the gena to the eye and most species will pass the test but if you compare the 2 images above you will see that <em>Carcelia iliaca<\/em> causes problems: <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Eye very large &#8211; approximately 12 times the height of the gena &#8230; <em>Carcelia<\/em> &amp; <em>Senometopia<\/em><\/li>\n\n\n\n<li>Eye not more than 8 times the height of the gena &#8230; NOT <em>Carcelia<\/em> &amp; <em>Senometopia<\/em><\/li>\n<\/ul>\n\n\n\n<p>It&#8217;s actually a nice example of how the &#8220;easy&#8221; features that we try to use are not always the ones that apply best to the full spectrum of morphology in the group. In the case of the <em>Carcelia<\/em> there is a lovely feature we could use &#8211; the presence of bristles on the dorsoventral surface of the hind coxa &#8211; but as you can imagine, that&#8217;s very hard to see! <\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/tachinidae.org.uk\/blog\/wp-content\/uploads\/Carcelia-iliaca-2023-07-13-11-37-17-CSmoothing2m2.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"557\" height=\"484\" src=\"https:\/\/tachinidae.org.uk\/blog\/wp-content\/uploads\/Carcelia-iliaca-2023-07-13-11-37-17-CSmoothing2m2.jpg\" alt=\"\" class=\"wp-image-1569\" srcset=\"https:\/\/tachinidae.org.uk\/blog\/wp-content\/uploads\/Carcelia-iliaca-2023-07-13-11-37-17-CSmoothing2m2.jpg 557w, https:\/\/tachinidae.org.uk\/blog\/wp-content\/uploads\/Carcelia-iliaca-2023-07-13-11-37-17-CSmoothing2m2-300x261.jpg 300w\" sizes=\"auto, (max-width: 557px) 100vw, 557px\" \/><\/a><\/figure>\n\n\n\n<p>This photo, cropped from the above full lateral shot, shows the feature nicely but most specimens are not as obliging and you need to usually look along the underside of the abdomen, between the hind legs. <\/p>\n\n\n\n<p>So, we still use the gena\/eye ratio in the key for most UK species but just bring <em>Carcelia iliaca<\/em> out earlier and in a different path.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>With the spread of the invasive Oak Processionary Moth (Thaumetopoea processionea) there has been a lot of interest in its parasitoids.
