I was starting to suspect the same, as Dr Hamilton mentions O canadensis has a striking pattern on the venter, which on this specimen is quite evenly orange throughout. Also that O canadensis is more "boreal" in character, but the northern section of the park may well be boreal enough to qualify, so we are going to investigate up there in the coming weeks. As for T lyricen in the region, I have now seen the image in a book just recently published and it indeed closely resembles those images of T lyricen on Bug Guide. It was found in 2007 in Richibouctou, a village at the southern edge of Kouchibouguac National Park by Alexandre Brideau. This was reported in "Assessment of Species Diversity in the Atlantic Maritime Ecozone. 2011. Edited by: McAlpine D.F., and Smith I.M. NRC Research Press. Ottawa, Ontario". I know Alexandre Brideau and have met him once or twice. I will look him up and try to find out more about this intriguing record, and will also definitely be on the lookout for all cicadas from now on! I am also learning my Cicada calls as we speak!
