The Question: I saw this spider(?) walking on the ceiling of my kitchen. It was too small to see distinctly, but I grabbed my camera and got a good shot with my telephoto lens. It’s a fearsome looking little thing! Anyway, I live in Georgia and there are lots of spiders around the house and in the house these days. This little bug was about 1/4″ long from head to tip of tail. Is it dangerous?

The Short Answer: Manuel, you have nothing to fear from this little guy. It’s a jumping spider, from the genus Metacyrba. G. B. Edwards, spider curator at the Florida State Collection of Arthropods, and an expert on this particular genus of spiders, believes that your photo is of a juvenile Metacyrba taeniola.  It isn’t at all dangerous, so you’re safe.

These spiders don’t have common names, other than “jumping spider” (but there are thousands of species that are called “jumping spider”). You can find a close-up picture at


Dr. Edwards’ paper on the identification of Metacyrba spiders can be found here: It’s a fairly technical paper, but if you’re knowledgeable about spider anatomy and identification, it details the latest word on separating the species of Metacyrba.

My special thanks to Catnip and Eric at, who very quickly responded to my request for assistance. Catnip speculated that the spider might be a Metacyrba, and was right on the money.
