Description: Girdle on a mesquite twig created by Oncideres rhodosticta. Arroyo Chico, Tucson, Pima County, Arizona, USA. 18 October 2008. When you see a fresh girdle like this, there are likely mesquite girdler eggs in the distal part of the twig. The mother beetle chews this ring around the twig so the tip of the twig dies and the tree's resin cannot drown her offspring. The grubs develop in the dead twig and usually also pupate and overwinter in it. Date: 30 October 2011, 00:52. Source: Mesquite Girdle. Author: Katja Schulz from Washington, D. C., USA.
