\u00a0\u00a0 Scott Gilmore writes:\u00a0 I have a poor photograph of a new to me long horned beetle – \u00a0Evodinus vancouveri<\/em><\/strong> \u00a0– which my son and I found at Mount Washington Sunday May 10.\u00a0 Jeremy Tatum comments:\u00a0 I don’t suppose many viewers will agree that this is a “poor” photograph!<\/p>\n

\u00a0\u00a0 Here are some photographs of Pholcus phalangioides<\/em><\/strong> from Jochen M\u00f6hr in Metchosin.\u00a0 They are quite remarkable. \u00a0One of them shows the cast skin of the spider.\u00a0 How does it carry out such a delicate operation and leave the cast skin apparently undamaged?\u00a0 \u00a0Another of the photographs shows the spider eating something.\u00a0 Although we can’t be sure of what it is having for dinner, it does look rather like the spider Eratigena<\/em><\/strong>.<\/strong>\u00a0 <\/strong>But how can such a delicate spider as Pholcus<\/em> overcome and kill (if indeed that is what happened) such a huge, strong spider as Eratigena<\/em>?\u00a0 I asked Dr Robb Bennett about this, and this is how he replied:<\/p>\n

 <\/p>\n

Yes, a young Eratigena<\/em> or Tegenaria domestica.<\/em>\u00a0 \u00a0Pholcus<\/em> (and various theridiids) are well known for taking down quite large prey. I used to survey for Eratigena agrestis<\/em> and duellica<\/em> population by quickly checking theridiid webs around building foundations and window frames.<\/p>\n

 <\/p>\n

Answer to moulting “how?” is “very carefully”! I believe there is much under-skin enzymatic action happening to grease the wheels, so to speak. And all parts of the spider are very soft and malleable during and after the moulting process. Skin and all major and micro setae harden up very shortly after the spider emerges. Interesting that the moulting procedure is fairly standard across the phylogenetic spectrum of spiders \u2013 first pop open the top of the carapace like a hinged manhole cover, then slowly wriggle the pedipalps and legs out of their old gloves and leggings, and then finally extricate the abdomen. Puff up a bit, then harden up, and good-to-go\u2026<\/p>\n
