This week's WaynoVision comic features two mayflies mourning the passing of a member of their swarm.
The gag's basis is the fact that mayflies (or shadflies) live very short lives, from a few minutes to a few days. They're members of the delightfully-named order Ephemeroptera, which means "lasting a day." They apparently move quite fast to be able to carve a tombstone and bury their buddy before they themselves pass on.
This isn't the first time I've explored the mortality of insects in a comic. Four years ago, during a run as Dan Piraro's Bizarro guest cartoonist, I showed an imagined scene in Insect Heaven.
Next Monday, WaynoVision will celebrate the 78th birthday of country music legend Merle Haggard. Be sure to tune in.
