Hellgrammites: even their name sounds scary. But as frightening as they may appear, they are among the more innocuous insect larvae you are likely to see in Maine. Found under rocks in rivers or streams, hellgrammites are the larval stage of dobsonflies, which appear equally ferocious. Looks aside, dobsonfly larvae are probably best known as one of the best baits for bass fishing in Maine. Additionally, they only live in clean, pollution-free river water, making them a great indicator species of the water’s quality.
