Bald-faced hornets can grow up to 3/4" in length.  They live in meadows, forest edges and around lawns.  the adults drink nectar, fruit juices and even other insects.  The larva eat pre-chewed insects passed to them by the adults.  Adults are very protective of the nest and they will sting repeatedly if the nest is disturbed.

Older queens, workers and the young all die once winter arrives.  The young mated females survive by leaving the nest and hiding in the soil or in litter.

Digger Bees come equipped with a very long tongue for probing down into flowers.  They love nectar so they can be found in gardens and meadows.  They construct a nest in clay or sand and build a chimney for a entrance.

Five-banded Tiphiid Wasps live in meadows fields and lawns.  They are found throughout the United Stated and Canada.

Paper Wasps live in meadows, fields, gardens, and even near buildings.  They drink nectar and juices from crushed and rotting fruits.  Adults build paperlike hanging nest made of wood pulp and saliva.  Only the mated young queens survive the winter.  The rest of the colony die.

They tolerate humans better than hornets and yellow jackets so don't be in such a hurry to destroy them because they can be very fun to watch.

Yellow Jackets live in meadows and usually nest in the ground or at ground level.  The adults love nectar and feed pre-chewed insects to their larva.  They enjoy invading picnics and will actually carry off small pieces of food. 

They are very aggressive and will sting repeatedly at the slightest disturbance.  Avoid them at all cost.
