Index of Subjects --Apple-Mail-52-892934222 Content-Type: text/plain; charset=US-ASCII; format=flowed; delsp=yes Content-Transfer-Encoding: 7bit Hi Jim, The Fireflies of Ontario: http://www.biology.ualberta.ca/bsc/ejournal/lmb_16/lmb_16.html Was just published on 2 June 2011. Nevertheless Luk, Marshall, & Branham's treatment of Photuris in Ontario: http://www.biology.ualberta.ca/bsc/ejournal/lmb_16/lmb_1616.htm Is simply based on historical nomenclature and taxonomy, so (except in relation to Nova Scotia where they mention Photuris fairchildi) they call everything else in Canada Photuris pennsylvanica. James Lloyd and Marc Branham, the two foremost experts on lampyrids in North America, have a paper in press sorting out at least some of the confusion in relation to the name "Photuris pennsylvanica". In much of North America it may still be impossible to say with certainty what a particular Photuris specimen is until Lloyd & Branham actually publish their revision of the entire genus, which although its been on the books since at least 2002, still isn't anywhere near completion. Photuris is really complicated genus since many species look superficially almost identical, and even comparing genitalia won't always allow you to separate them. The concept of "species" as it applies to this genus, has been developed by James Lloyd who feels that male-contact flashing-patterns allow one to distinguish between species. It's a complicated formula that takes into account the number of flashes, the flash duration, the intervals between flashes, and the intervals between pulses (repeated flash patterns given by males). It's made more complex by virtue of the fact that the exact timing varies according to ambient temperature. Males also flash at different times in the evening, and in different species males fly at different heights and execute different flight paths in the air. Identifying Photuris makes identifying just about anything else seem trivial in comparison. My paper still need be reviewed (and who knows how quickly that will go), but mid-fall is probably a reasonable estimate. Cheers!
