I just found this critter with the very long antennae sharing my bathroom. My initial response was to channel Arnie in Predator - WTF are you? Since it seemed in no hurry to go anywhere I found my camera, took some shots, then gently deposited it outside. Was that a good deed or a mistake? Is this a harmless, useful critter or a nasty I should crush on sight next time? Still fairly new to Florida, and there are sooooo many bugs to learn - help please!!!
