Of course, we have received many more pictures from readers than those shown above, but we sometimes have difficulty identifying creatures in images with a high degree of confidence. So, in this guide we only provide pictures of creatures that, one, we can positively identify and, two, are common enough that multiple readers have asked about them. This is obviously not a comprehensive guide to worms and larvae, but it should help people identify some of the most common worms and larvae.
