ÒAdults are about 3/4 inch in length and are dark brown
with a whitish to yellowish stripe across the central part of the back. The hind legs have flattened,
leaf-like expansions on the tibia. Nymphal stages look similar to adults except that they do not
have fully developed wings.
ÒA leaf-footed bug in the genus Narnia is
common on prickly pear cactus. Another species, Acanthocephala declivis (Say), is one of the largest true bugs in Texas, being
over an inch in length as an
adult. Adults are particularly active in the fall. Although some members of
this group are predaceous,
immature stages can be easily confused with assassin bugs (Reduviidae).
