This Carpenterworm Moth (a first for me) was hanging out by my porch light on Independence Day. What a firecracker! 
Bugguide.net say the females can have a wingspan of over 3 inches.  The wood-boring Carpenterworm Moth larvae are very
destructive to living trees, damaging otherwise healthy wood for lumber and causing your favorite yard trees to bite the
 dust earlier than planned.  © Carol Davis, 7-4-2009
