Opilio canestrinii a species of harvestmen stood over a spider egg sack, from which it was feeding. The harvestmen stayed near to this food source for a couple days returning each evening to feed from it. Bad weather or predation dislodged the harvestman and a few days later, spiderlings emerged from the egg sack.

Whether it was feeding on the egg yolk, unhatched young or both, I couldn’t tell. Little is known about the feeding behaviour of this species, most opinions species are opportunistic scavengers.

Zero posting here for a while from, far too focused sorting and filing 12 yrs worth of photos. 😒😳
HNY to all followers and here’s an #opilione pic from winter 2021.
