Here is an excellent example of the ant-acacia mutualism that Bagheera kiplingi (and possibly Frigga crocuta) exploits. Take special note of the soil surrounding this Vachellia plant, which is completely stripped of vegetation. This was the work of Pseudomyrmex ants that do everything possible to make sure their plant thrives--including clearing away the competition!
The spider Bagheera kiplingi is 90% vegetarian in Mexico, and 60% vegetarian in Costa Rica. I will test if population density causes this difference by documenting population density of spiders in both countries and artificially increasing the number of spiders per plant in Costa Rica to compare with results in Mexico. In Panama, I will video record and collect samples of Frigga crocuta, which exhibits similar habits to B. kiplingi and might also be vegetarian.
