Hello! rvanderweele wrote: Looks to me as a Mitopus morio I don't think so. This is a short legged one with a different marking. In central Europe at this time of the year it would be a juvenile Rilaena triangularis (a species adult in spring; most other harvestmen are summer or autumn animals), but I don't know the species of the Shetlands.

Rilaena is indeed a spring species. I cannot see the palps well. As far as I know fromRoger only Megabunus diadema is known from the Shetlands. Anyway,Roger, in case you can collect coming spring some harvestmen for me, I will be pleased to look at them. ruud van der weele rvanderweele@gmail.com |

BTW, Juergen, I checked quickly. You are right. Problem with Mitopus, which may occur in the shetlands, I think, that it is extremely variable in colour. I have seen them very light, like the one on the photo, to almost blackish. But looking at the figure on the body...yes, you are right. I've got to say, when writing my first reaction to Roger I thought at that moment how strange it is to see a Mitopus on the ground. Mitopus morio may be found typically on bushes, etc, so not on the soil level. Rilaena, especially juv may be indeed found on the ground. Adults more frequent on vegetation. BTW, be careful, juveniles may have shorter legs than adults. ruud van der weele rvanderweele@gmail.com |

Hi Guys slight misquote there Ruud, I did in fact say "None on the Checklist, but I have found several, the best looking one being a tiny 3mm Megabunus diadema, which I had ID'd on D.info." This one was photographed on 4th August last year. Other ones were..http://www.dipter...post_82271 http://www.dipter...post_82655 http://www.dipter...post_82941 EDIT; As can be seen, the one ID'd as M.morio is at ground level also.

Sorry, by writing " known from the Shetlands" I meant recorded from the Shetlands. I know that Roger saw more species. I thought that M. diadema was recorded...well apparently not! Maybe nice to work on a small article about the Opilionid fauna of the Shetlands, Roger? For me M. diadema is a great looking animal. I only found it in Norway. I looked for it in the Netherlands, always in vain! cheers, Ruud ruud van der weele rvanderweele@gmail.com |
