The oak gall of a Heteroecus sanctaclarae wasp. The wasp eggs triggered the oak to grow a structure that both protects and provides a food source for the developing larvae. At James San Jacinto Mountain Reserve, students studied the distribution of galls across co-occurring live oak species. They found a total of 4,623 individual galls on 60 different oak trees: 3,805 (82.3%) were found on canyon live oak, while the remaining 818 (17.7%) were found on interior live oak. Canyon live oaks not only showed significantly higher gall densities, but also greater gall wasp species richness. Photo credit: Nicole Schriber
