This wandering phenomenon is fairly well understood in insects that feed above the surface and then &#8220;wander&#8221; to the soil in order to start their immobile pupal stage in the soil, that could well be what we are seeing here, this particular behavior in LeatherJackets is not something I can find any reference to in any papers but I will ask around.<\/p>\r\n\r\n\r\n\r\n<div class=\"wp-block-image\">\r\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" class=\"wp-image-5441\" src=\"https:\/\/greencastadvisory.com\/wp-content\/uploads\/2021\/04\/WhatsApp-Image-2021-03-30-at-06.55.06-edited.jpeg\" alt=\"\" width=\"382\" \/><\/figure>\r\n<\/div>\r\n\r\n\r\n\r\n<p>The thing I&#8217;m really interested in when the do hatch is what species are we seeing &#8211; for an in depth ID guide <a href=\"https:\/\/greencastadvisory.com\/2020\/05\/08\/cranefly-id\/\">click here&#8230;.<\/a> but in short:<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>Female \u2013 Shorter wings, Separate eyes = paludosa<\/li>\r\n<li>Female \u2013 Longer wings, Eyes connected = oleracea<\/li>\r\n<li>Male \u2013 don\u2019t bother trying<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p>We should only see the oleracea hatching in the spring which (assuming it&#8217;s female) has wings longer than the body.
