Yellow jackets are easily recognized but are often confused with
paper wasp.  In south Texas, yellow jacket nest size may vary
from a few inches to 6 ft or larger. Yellow jackets are primarily
ground nester's, but they also construct aerial nest. Nest may be
found in gardens, flower beds,  pastures, road side
embankments and elsewhere. Aerial nest are typically in trees,
voids of buildings and under eaves.

Because of their scavenging behavior, Yellow jackets are a
menace around parks, camps and suburban sites where people
leave open food and discard garbage. Yellow jacket workers
forage to feed their larvae insects and spiders. They also gather
nectar, honeydew and other carbohydrates, but they do not
store honey as do bees. They emerge during the early spring
and build small paper nest in which they lay eggs. After  the
eggs hatch, the queen feeds the larvae for about 18 to 20 days.
