No, we just caught one in my front yard. It is not extinct.
they form big groups and wene predters come they atack and ther is a fest right ther.
dobsonfly live near bodies of water for that most part, they spend most of their lives in the larval states as water creatures, when they grow up they live for only seven days or so and primarily live near the body of water from which they were born.
If it's the same thing we called a "helgermite" back when I lived in WV, it's actually called a Dobsonfly. They are a variety of insects native to the Americas, Asia and Africa.
Dobsonflies eat small bugs and some plants
I found a few good pictures and some information at the following site. http://insects.tamu.edu/fieldguide/bimg121.html
There are many different types of larvae and they eat different things that include leaves from various plants like milkweed. Some larvae eat meat and others eat insects like aphids.

Moles bury themselves for two reasons for nests and protection. Two types of tunnels for protection are surface runways and deep runways.
