Johnson Jumper Spider

Phidippus johnsoni


Large female Johnson Jumper Spider approximately 1 cm long. Hunting on my hydrangea plant.


Urban house flower garden.


The red-backed jumping spider (Phidippus johnsoni) is one of the largest and most commonly encountered jumping spiders of western North America. It is not to be confused with the unrelated and highly venomous redback spider (Latrodectus hasselti). When threatened, the redbacked jumping spider can inflict a painful bite in self defense, but with no serious medical consequences. Wikipedia

Thank you ForestDragon and sorry about adding it to the wrong mission.

This is a great spotting! I love these guys. I haven't seen a Johnson yet here.
I just wanted to let you know that I have removed this spotting from the Lost Ladybug mission (since it isn't a Ladybug).
