While I was walking around the house that's still under construction, and when I made it to the road in front to get a good look at the front, I heard a very familiar sound. Buzzing from the trees! That was the first time I'd heard that noise here in the Philippines. I asked my mother-in-law about it and she said that noise happens every year. Well, if they're cicadas, it certainly would. So… I did some investigating and yes, that's exactly what I heard. Afterward, I went to wikipedia and looked them up:

Cicada
From Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/Cicada:

A cicada is any of several insects of the order Hemiptera, suborder Auchenorrhyncha, in the superfamily Cicadoidea, with small eyes wide apart on the head and transparent well-veined wings. Cicadas live in temperate to tropical climates, where they are one of the most widely recognized of all insects, due to their large size and remarkable (and often inescapable) acoustic talents. Cicadas are sometimes called "locusts", although they are unrelated to true locusts, which are a kind of grasshopper. Cicadas are related to leafhoppers and spittlebugs.

Here's a picture from there:

Some people think they're gross, like any other bug. They don't bother me. Heck, cats and dogs eat them! Me and my brothers, when we were children, used to put strings around them and fly them around in circles like those old gas-powered airplanes!
