ii) I spotted this beautiful beetle on Verbena Bonariensis this morning:
I had no idea what he was but posted him on Facebook so my friends could see him and one of them (thanks Mandy) did some research and found that he's a pollen beetle named 'Swollen-thighed beetle', Oedemera Nobilis. We now know that it's a male because of the bulges on his legs.
Oh that glorious colour! He has to be one of the most attractive beetles I've seen so far this year.
