Comments & ID Thoughts

These spiders seems to hatch/migrate between February and March. I'm really curious as to what kind they are.

This is not a true spider but part of a related order of Arachnids, the Opiliones. There are called Harvestmen or Opilionids and differ from the true spiders in that the cephalothorax (the head end) and the abdomen are fused together to form a ‘one part’ body, where spiders have a distinct cephalothorax and abdomen. The Harvestmen normally feed on dead and decaying plant and animal matter and may prey on very small invertebrates.

Hi…I just sent in a photo of this spider wondering what type it is. I have seen about 7 the last week on my back porch outside by sliding door..no webs or foliage area. I live in Havasu AZ. I have a little yorkie and wanted to know if they are Harmless??

Hi, your photo appears to be the same species as this one, so the information here applies if it is the same. They are not dangerous to your dog or humans.
