|On June 5 2011 I posted an image of this species, incorrectly identified as Lytta aenea
Today, May 24 2017, I saw this one, Lytta sayi, feeding on the flower buds of a cherry (Prunus sp.).
These beetles are very dangerous to handle as they can exude blood, containing cantharidin, through their leg joints; a process called reflex bleeding.
Lots of information on cantharidin in Wikipedia, the least of which is causing skin blisters. In the USA it is classified as an "extremely hazardous substance"

Quote – Holmes on ‘Entomology’
” I suppose you are an entomologist ? “
” Not quite so ambitious as that, sir. I should like to put my eyes on the individual entitled to that name.
No man can be truly called an entomologist,
sir; the subject is too vast for any single human intelligence to grasp.”
