Dragonflies are some of the largest insects that we see in our backyards; however, they are much smaller than their ancient relatives.

       The largest dragonfly alive today has an impressive wingspan of about five inches.  However, the size of modern-day dragonflies is considerably smaller than some of their ancient relatives.

       Remarkably, scientists have unearthed 300-million-year-old dragonfly fossils with wingspans that are more than two feet wide.

       Wow!  If the dragonflies in my backyard were that large, I would be afraid to leave the house.
