Found by Alice Abela during a very rainy morning on the somewhat sheltered wall of a gas station. Presumably it was lingering there after coming to lights in the small roadside town of Jacob Lake the night before (Selander(1) mentions that P. palpalis is much more active at dusk and night than during the day).

I think all in our group (Alice, Margarethe, Robyn, and myself) recognized the genus as Pyrota when we first saw this meloid. According to Selander(1) the trifasciate elytra indicate the Mylabrina species group within Pyrota, and using the key there, this went to P. palpalis. That said, the 1st couplet of the key (on pg. 672) seemed puzzling (i.e. descriptively inaccurate)...but only one alternative was consistent with the characters in subsequent couplets. Agreement with the description and all other info on P. palpalis in that paper is excellent...as is agreement with the existing BugGuide posts of that species. In particular, the ivory base color of the elytra; the immaculate head (in particular, occiput); and the two pairs of spot on the pronotum are useful characters. The range map on pg. 677 indicates a record not far from the locale here.

From the information in Selander(1), I believe the large 3rd palpal segment indicates this is a male.
