Last weekend my husband and I set off to the IJssel river forelands to take a walk. And of course I had to look for harvestmen along the way.
I especially went looking for Astrobunus laevipes, a small harvestman (2,5 – 4 mm) with two rows of blunt spikes running over its back. It is an originally southern European species, that has been found for the first time in the Netherlands in 20031. It is expected to live along the IJssel, but the area has not been searched often so it has not (yet) been found. We turned over many small rocks, but unfortunately weren’t able to detect one.
