Unfortunately, no one was able to claim the prize for my recent (and never-to-be-repeated) $1000000 (did I forget to mention that?) ID Challenge. The mystery knee that I
had no clue about featured a couple of weeks ago belonged to Habronattus cuspidatus (“cuspidatus”, from the Latin, ” provided with a point”, or “tipped” ), a tiny jumping spider that I found in Dinosaur Provincial Park on the 29th of May this year. Looking down on it from above, it appears undistinguished, but like many of the Salticidae, it is when you meet it face to face that you can really appreciate its charms.
Because this spider is so small and so active, it is hard to get both the eyes and those lovely ornamental knees in focus at the same time. It would certainly be interesting to see how this type of ornamentation is used by the spider during courtship.
