A little later she came out of her burrow and showed off her full magnificence. Tarantulas have an interesting defencive capability in addition to venom. Some of the hairs on the top of the abdomen are specialised for defence. These hairs, are tipped with backward pointing barbs. If a tarantula is threatened in any way, it brushes these hairs into the face, paw or other body part of its attacker. Once these hairs are embedded, they are irritating and very difficult to remove because of the barbs.
And to end with, something less fearsome! This is a Mesquite Twig Girdler and it might not be scary to humans but you can be sure that Mesquite Trees are not keen on this little character! The adults emerge in August as the monsoon season is winding down, mate and then select a mesquite, or sometimes an acacia, as home base. The female then proceeds to chew a ring around a twig, stopping the flow of sap and eventually causing that part of the twig to die. She has prepared a nursery for her offspring, allowing her to lay eggs in the dead part.
Sweet dreams everyone :)
