Scott Powell’s comment on my post about ant-like jumping spiders provokes me to take a break from our current field trip in Mexico to write a post about one of the most stunning cases of mimic-model matching I’ve seen in salticid spiders. On a trip to the Dominican Republic in 2009 we found a fair diversity of jumping spiders of the genus Peckhamia. In one locality we found this ant and this species of Peckhamia.
In another locality we found this ant and this species of Peckhamia. Notice that the front legs of the spider are tipped in red, just as are the sides of the face and the mandibles of the ant. Wow.
