"The deadly warfare between mankind and the insects never ends. Every  minute of the day and night, billions of them are attacking our crops, orchards, forests and grasslands. They attack our homes, gardens, and even ourselves. Of those that were inadvertently brought to the United  States from foreign countries, one of the most destructive is the  Japanese Beetle."       Courtesy: http://www.newton.dep.anl.gov/natbltn/500-599/nb579.htm

 While perusing the Internet, I came across a florid paragraph of mankind vs the insects and I reproduce it here for your entertainment.
