College Station, Texas, June 8, 2022  Oak leaf galls (specifically from the gall wasp Belonocnema kinseyi or a related cynipid species) at Lake Somerville Trailway near Birch Creek Unit of Somerville Lake State Park. Ants harvest the galls, carry them back to the nest to consume the nutritious outer layer, and often discard the hard inner "seed" (which contains the wasp larva) unharmed. This is a newly discovered form of "myrmecochory" (ant dispersal) where the gall wasp manipulates the ants to transport its offspring to the safety of the ant nest.

College Station, Texas, April 18, 2022  Spotted leaves of Chinese Tallow exhibiting a phenomenon known as the "green island" effect.

As a result, while the rest of the leaf receives the signal to shut down for winter (losing its green chlorophyll and revealing the red anthocyanin pigments), the infected "islands" stay green and photosynthetically active.
