Callobius Spider

The Callobius Spider is also called the hackle mesh weaver (callobius serverus). They commonly build irregular-looking webs, in bark and wood debris. They can be found on Vancouver Island. I hardly ever see them around our home, but often run into them, while out in our Island forests.

They are very similar to funnel web spiders, although those spiders mostly build their webs in grass & gardens around our house.

Both can live through the winter. Funnel-web spiders will move into our home when it gets chilly, but with our mild winters, hackle mesh spiders usually find a safe place under logs and rocks.

Physically speaking, they tend to have a 2-toned body, with a shiny-looking cephalothorax, and fuzzy abdomen with a pattern. The red cephalothorax of the spider in the picture is a good field identifier for the largest members of the Callobius genus.

These spiders are very beautiful to look at and can reach a fairly good size when food is ample and winters are mild.

  1. Thank you for saying it is a beautiful spider because it truly is
    They are very docile too. I just took one outside that had scaled the washroom towel ( to drink from the sink during this drought we are in )
    It didn’t move until I got it safely onto a tree stump in my yard.
    I have also allowed one to remain in the kitchen vinyl window frame after watching it capture a big wasp , swiftly wrap it up and whisk it into the space under the window.
