Positives for human interactions/ecosystem • They are good indicators of clean water. They need clean water for breeding, if you have a lot of black flies that means you have clean running water. • They are pollinators. The males dine only on plant nectar and sap. They get this food in part from our earliest spring wildflowers, and they pollinate as they go. They may be responsible for pollinating some of our blueberries. • They are a good food source, bats, dragonflies, flycatchers and swallows are a few of the critters that eat them. http://bugguide.net/images/raw/60S0U0FQM0JQYKNRJKDQJKVRJKUR3KOQE0L0W000P0H0XQARZQYRMQFR7QDRW0YR0QK0MQ1RIQ00.jpg
