Opilio parietinus - recently moulted subadult female (close-up) We had thought this species to have gone completely extinct in the Netherlands but a few years back Jinze Noordijk found a relict population in a tunnel in Limburg and a few month later I found a population on a brick wall under a fly-over of a busy highway smack in the middle of Rotterdam. The population in Rotterdam has now vanished, probably due to graffiti &quot;artists&quot; spraying the wall with paint and some other party cleaning it off later with chemicals and high pressure water. <br />
This image was taken in Rotterdam 2013-07-18 before the population was eradicated.<br />

Opilio parietinus - recently moulted subadult female (close-up)

We had thought this species to have gone completely extinct in the Netherlands but a few years back Jinze Noordijk found a relict population in a tunnel in Limburg and a few month later I found a population on a brick wall under a fly-over of a busy highway smack in the middle of Rotterdam. The population in Rotterdam has now vanished, probably due to graffiti "artists" spraying the wall with paint and some other party cleaning it off later with chemicals and high pressure water.

  1. Beautiful! Posted 11 months ago
    1. Hi Lisa, thanks - she was clearly resting from the extremely strenuous and delicate process. Too tired to try and get away :o) Posted 11 months ago, modified 11 months ago
  2. I hope there may be more in natural caves or abandined war shelters...I don't know if you have many of these in Holland. We do in Belgium but I have never noticed the harvestmen. But actually I saw harvestmen mimetizing very well in bark trees in woodlands near my home. Posted 11 months ago
    1. Yes, the two place where we had found the relict populations are quite "inhabitable" - always dark with no sunshine getting in, unpleasant winds/drafts etc. Also both have old brick walls with deep (decaying?) joints and loose patches of mortar or cracked bricks. Old concrete walls (also present at the location in Rotterdam) were not inhabited except for one or two "strays" maybe. I have reports from Germany of populatons sitting in the cellar area of north facing walls of old brick buildings (also: no sunshine ever, damp and generally unpleasant), so that is the sort of habitat that is obviously avoided by the southern European newcomers that have clearly won the competition for the "better" locations.
      So, do go and give places like that a better look! :o) Adults can be found roughly from July to November ...
      Cheers, Arp

  3. She's gorgeous. Glad you found her before they disappeared. Posted 11 months ago
    1. Yes, she still had all the chances of living a fruitful life and procreate - this was 2013 and the habitat/pupulation must have been destroyed some time in 2017. Posted 11 months ago

''Opilio parietinus'' is a species of harvestman. It is found in Europe and North America.

It is similar to ''O. canestrinii'', but has dark spots on its coxae, and is generally more of a grayish green color. Like ''O. canestrini'' it was often found on house walls in central Europe, but has by now almost everywhere been replaced by this invasive species.
