Photuris forresti is an amazing firefly easily distinguished by its unique flash-chain patterns. P. forresti males fly above swamp land creating intricate flash-chain shapes, displaying patterns like loops, sine waves, and v shapes (see photo 5 for an example). Time between flash-chains are erratic. individual flash-chains can include anywhere between 5 and 9 flashes in either a dot or dash form. Male P. forresti do not have elytral stripes, and generally have a red pronotum with central black arrow, though Lynn Faust has noted considerable variation between male pronotums. Graph paper is provided for scale, 5 boxes per inch.
P. forresti is currently listed as endangered on the IUCN Red List, G1 - critically imperiled on the NatureServe status, and petitioned for listing on the U.S. Endangered Species Act.
The biggest threat to this species is habitat loss, followed by light pollution. More research is needed to understand how widespread this species can be found.

Raríssima e pouco conhecida, essa planta parasita fungos micorrízicos. São conhecidos apenas dois indivíduos que estão depositados em uma coleção cientifica do Rio. Essa é a primeira foto na natureza dessa espécie.
