The European hornet that has been imported into the U.S. is increasing
it's distribution.   Ten years ago when I was working in an Extension
Office in southeasten Indiana a client brought one in to be identified.
It was the first time I had seen one.  The entomology specialist at Purdue
told me they had a few reports in southern Indiana of the hornet, but
that they normally prefered deeply wooded areas.  Those living near tracts
of timber were more likely to see them.  They indeed do fly at night,
at least on moonlite nights and also around outdoor security lights.
The bald faced hornet that builds the paper nest in trees do not fly at
night.  The European hornet does have a nasty sting and should be avoided
if at all possible.
