Daily Botanical: Soldier Beetles on Black Eyed Susans

Yesterday, while visiting a series of test gardens, I witnessed legions of these gold and black soldier beetles (Chauliognathus pensylvanicus) aka Pennsylvania Leatherwing beetles squirming, frolicking and procreating up a storm all over a bed of ‘Tiger Eye Gold’ Rudbeckia.

As I moved around the beds I observed that they only inhabited the flowers that perfectly matched their body colours. Interesting tactic for safety since they are likely quite vulnerable during these frenzied acts reproducing the species. When not procreating, I’ve read that the adults eat pollen and specifically enjoy goldenrod. However, this was a HIGHLY cultivated property and there was nary a goldenrod in sight.

“Penis flower” is too hardcore for work? Do you work in an office with small children?

I gotta say, I’ve always been a big fan of the penis flower, especially for work.
