| The tiger beetles (family Cicindelidae) are members
of the suborder Adephaga within the Order Coleoptera. Adult tiger
beetles are characterized by large, prominent compound eyes and
eleven-segmented, filiform antennae. The antennae are inserted on the
frons above the clypeus and below the eyes. The head, at the eyes, is
wider than the pronotum (in most common genera of cicindelids). The
tarsi are five-segmented.
Adult beetles of the families Cicindelidae (tiger beetles) and Carabidae
(ground beetles) are quite similar morphologically, and some
entomologists place the tiger beetles in the subfamily Cicindelinae
within the family Carabidae. The ground beetles differ in the following
ways: antennae inserted above the mandibles to the side of the clypeus,
and below the eyes. Most ground beetles have a head, at the eye, which
is narrower than the pronotum.

Body length is typically 9-11 mm.
Dorsal surfaces are coppery with large maculations over
much of the elytra. White setae cover much of the head
and pronotum. Habitat is commonly dry white sand areas
including trails, road edges, and open areas with sparse
vegetation.
This tiger beetle ranges from 10.5 to
13.5 mm (0.41 to 0.53 inches) in length. Like
all tiger beetles, its legs and antennae are
long and slender and its jaws are large. The
elytra (wing coverings) are white with narrow
sinuous bronze markings; the head and pronotum
are bronze. The pronotum and sides of the under
surface are densely covered with white hairs.
The sides of the elytra of males are nearly
parallel whereas females are somewhat more
broadly rounded. The pale coloration renders the
beetle well camouflaged on the light sand where
it lives.
