Was mowing one day and saw a cicada drying it’s wings on a Walnut tree.
I returned a couple hours later to check up on the cicada and found a jumping spider feeding on the cicada.

Bold Jumper eats Cicada

Hi Chris,
We are very impressed with both your photograph and what it documents.  We believe the spider is most likely a Bold Jumper,
Phidippus audax, and based on the information on BugGuide, it is a highly variable species, though BugGuide does indicate:  “The majority of audax specimens are black with three white spots.”  There are also some excellent images and information on this Cirrus Image website.  Alas, your photos do not provide a clear dorsal view of the abdomen, so only one white spot is visible.  We have so much room to speculate upon how this Bold Jumper managed to capture a Cicada many times its size.  We wish you hadn’t cropped the photo.  It appears that this might be a newly metamorphosed Cicada.  The Cicada is lighter in color when it first metamorphoses.  Also, insects are much more vulnerable immediately following molting and the metamorphosis process.  The exoskeleton will not have properly hardened immediately after metamorphosis and the Cicada is incapable of flying until after its wings and exoskeleton harden.  That would be the window of opportunity for a proficient hunter like the Bold Jumper to tackle a significantly larger prey than it would normally be able to take.  Thanks for sending us your photos.

    Love your web site. It was referred to me by a co-worker after I found a new spider in a rose bush. I Googled spiders & searched fruitlessly for hours. Today I spent just a few minutes on your site & found my spider. It’s a Bold Jumper….big, black, stocky with the signature bright green fangs. Egg sac looks like a cotton ball. We put her back in the garden. She went into the egg sac & sealed herself into the bag with her eggs. Very cool. Can hardly wait to see the babies. Are they at all dangerous to humans? Just wanted to know how much of a distance I should keep between us. She didn’t seem at all agressive…almost docile. Please advise. Thank you.

      We are positively charmed with your polite comment. Jumping Spiders are not considered poisonous, but like most Spiders, they are probably capable of biting a human. We have never read any accounts of the venom being dangerous to humans. We are curious how you embarked upon your search once arriving on our site. Did you use our search engine typing in key words? Did you click Spiders and just browse through our reverse chronological order postings? Or, did you select the Jumping Spider subcategory?
