Cicada Skin - Diceroprocta biconica

Cicada Skin - Diceroprocta biconica
Big Pine Key, Monroe County, Florida, USA
July 20, 2009
Size: 1 inch

Tentative id - D. biconica
Given the locality, date of photo, individual submitting this image, and comparison of this image with reference specimens of the following (D. olympusa, D. viridifascia, and T. davisi), it is very likely this shell belongs to the species listed here, Diceroprocta biconica. This image along with 2 images of an adult have been submitted by this contributor (NOTE: D. biconica should be a fairly common and abundant species in this area during the months of July-August into the first half of September).

NOTE: For those of you with an interest in cicadas, please keep in mind that species identification of casts is often very difficult if not impossible without having the adult and its shell in hand. The placement of this image is based primarily for reasons listed above and are not absolute with regards to id.

Diceroprocta biconica (?)
Likely Diceroprocta biconica, "Key's Cicada"

The shells of D. biconica can be common on palms, as in this image... (esp. Thrinax radiata, Sabal palmetto and other misc. natives). In addition, the shells can be encountered on a number of other plant species - i.e. surrounding scrub vegetation (various vines and woody plants). The shells are approx. 1 inch long and slightly heavier in appearance than those of other Dicerprocta species, as D. biconica is slightly larger than others in the Genus. As I recall the front legs on the shells also seem a bit robust by comparison.

In discussing this species with Elias, who collected D. biconica specimens and shells years ago, it is likely this shell belongs here.
