[btwrpvds] Ecology of bug zappers

Electric bug zappers preferentially kill bugs attracted to the light.  It could therefore increase bugs not attracted to light, for example mosquitoes, as they expand to fill the ecological niche made empty.  Also, as it decreases bugs, it decreases food for bug predators, so decreases bug predators, which do not preferentially eat bugs attracted to light.  The decrease in predators could increase the prevalence of certain bugs.
