What is Cicindela?
Cicindela is a genus of vividly colored, predatory beetles in the subfamily Cicindelinae, commonly known as tiger beetles. While these beetles are not economically important, the are excellent indicator species. The Cicindelinae are also very popular with insect collectors and members of the family are quite sought after.
A number of Cicindela species in the U.S. are currently listed as endangered, threatened or candidates for listing; a full list can be found at the FWS web page. In addition there are Cicindela species listed as “rare species” by many states.
Two of the best books about tiger beetles are Pearson and Vogler’s informitive “Tiger Beetles: The Evolution, Ecology, and Diversity of the Cicindelids” and Pearson, Knisley, and Kazilek’s indespensible book “A Field Guide to the Tiger Beetles of the United States and Canada”.
