Now that it's getting warmer bugs are getting more active. I've got all sorts of bugs on the windshield. I'm not really sure what some of them are. Here in Tucson we don't seem to have the mustard bugs we had in Colorado. What's a mustard bug? They're these little yellow flying bugs that smash into your car and it looks like you got pelted with packets of mustard. Don't know the official name for them. So convincing are they, I was dating a woman back about 10 years ago and I actually convinced her that was where mustard came from--mustard bugs. Yep. Mustard actually comes from a little yellow flower that grows a number of places and is particularly common in Canada.
