Toumeyella mirabilis - Mesquite Scale (& Crematogaster ant)
Believe it or not, the large splotchy blob in the picture is an insect. Scale insects such as the Toumeyella pictured here are highly specialized feeders of plant juices and have lost many of the familiar external features of other insects. Many scale insects are ant-tended, and this one is being visited by a Crematogaster ant.
Thanks to Demian Kondo for the scale ID.
