Note the parasite.
No interactions present.
The red parasites on harvestmen are the larvae of Erythraeidae mites - those predatory red mites you sometimes see on dry walls & paths. One species, Leptus phalangii, is a specialist on harvestmen, but I don't know how to identify these.

Harvestmen with short legs on urtica: normaly
Oligolophus tridens, but the pic is suboptimal.
I am sure this is an Oligolophinae. But not sure that we can see a trident, could be some little tubercles like in Mitopus morio.... Legs have got some careneous edges but I am not sure that this is like in Mitopus morio. That why I propose Oligolopus. But color and spines on legs show more a Mitopus morio...
