Eastern red cedar and the critters that love it 

These are juniper berries on an eastern red cedar tree. 
The cedar waxwing (a songbird) loves to eat juniper berries. 

And the cedar loves for birds to eat its berries because they are more likely to germinate after passing through the bird’s digestive tract (some distance from the parent tree).

Other critters that depend on native cedar trees include the juniper hairstreak butterfly. 

Its green caterpillar is adapted to eat cedar leaves while camouflaging against the green fronds. 

The juniper geometer is another caterpillar specifically adapted to eat cedar and camouflage on it. The juniper geometry is brown and therefore camouflages against the dead fronds.
