While I'm usually the first to chime in on technical inaccuracies, I can 
certainly think of many insects that squirt liquid from their anus, and 
it isn't very uncommon for this to be referred to as piss, even if it is 
not what *mammals* do when they urinate. It's especially hard not to 
fall into that colloquialism when watching bugs like the glassy-winged 
sharpshooter; it is this behavior, after all, that earned them the 
common name "sharpshooter". ;-)
