At 47X, this scanning electron micrograph (SEM) showed the head, and some of the thoracic region from an anterior view of a female velvet ant, Dasymutilla sp.. Note the two anteriorly-placed antennae with their rounded "scapes" that are the most apparent head appendages. Like the antennae, the numerous hairs or setae adorning almost all of the insects exterior surfaces, act as sensory structures, supplying the organism with information about its environmental parameters. The jointed legs, from which the insect's Phylum Arthropoda is derived, i.e., Arthro = jointed, and poda leg, are also partially visible, emanating from the thoracic region.Created: 2007

Under a very low magnification of only 11X, this scanning electron micrograph (SEM) revealed the morphologic details of a female velvet ants, Dasymutilla sp., distal abdomen from which her stinger had been exposed. Another view of the exposed stinger can be seen in PHIL 9894. The female velvet ant is not really an ant at all, but a wasp, which merely resembles an ant, hence its name. Its sting is very painful, which has caused it to often be referred to as the cow killer ant. However, it was the post-sting festering wound, which would become infested with the now eradicated screw fly that would cause the cows death, and not the sting. Also see PHIL 4638, 6363, and 6364 for photographs of the ant revealing its coloration, and velvety covering of external chitinous hairs.Created: 2007

Magnified 54X under a scanning electron micrograph (SEM), this is one of the two eyes of a female velvet ant, Dasymutilla sp., with a number of debris particulates on its surface. Note the hairs surrounding the eye, which are actually chitinous extensions of the exoskeletal surface. In mammals, the hair is composed of another protein known as keratin. The hairs adorning an insects exoskeleton are known as setae, and interestingly, both, these sensorial setae, and its eyes, as well as its antennae all provide the organism with information about its environment, which allows it to act in accordance with its environmental elements.Created: 2007

Under a high magnification of 1175X, this scanning electron micrograph (SEM) focused on the distal tip of a female velvet ants, Dasymutilla sp., stinger. In PHIL 9881 and 9882, lower magnifications places this image into a context, which allows you to appreciate its orientation. This is the stingers tip, which is encased in this bulbous sheath, which may act to protect the delicate sharp tip from being damaged, which would reduce its effectiveness when trying to penetrate its victim.
