This is indeed a female March Fly. The Love Bugs that are well known in parts of Florida and the South are also March Flies, but Love Bugs, Plecia nearctica, which are pictured on BugGuide, are red and black. So, all Love Bugs are March Flies, but there are many species of March Flies that are not Love Bugs.
