  1. A wonderful photo and description, and so cool that you took the photo exactly when the male releases his pheromones. Posted 7 months ago
    1. Thanks Ferdy, I don't promise to always make such long descriptions, English is not my native language and I am not a biologist. Google translation being my only help, don't hesitate to correct me if you see errors. Posted 7 months ago, modified 7 months ago
      1. You're doing fine, Anne :) English isn't my native language either, and I'm definitely not a biologist either. Posted 7 months ago

  2. That’s so interesting, Anne! I have seen Hoplia beetles lifting their legs, but had no idea why they were doing it. Thanks for sharing! Posted 7 months ago
    1. It can also lift the legs if someone approaches too close or if another male is on the same plant. He will even try to dislodge it by pushing it backwards with those same legs raised. Posted 7 months ago
      1. Neat! Thanks so much for the added details. Posted 7 months ago
