This morning was straight out of a horror movie.  I was awoken by a cicada killer crawling on my face.  I have no idea how it got inside but here is some information on this scary looking insect.

“One of the largest wasps encountered; although females are capable of stinging, they are rarely aggressive towards man or animals; males are incapable of stinging, but can be more aggressive; large numbers of females nesting in localized areas such as sandy embankments can be a nuisance and cause concern because of their large size, low flight and nesting activities; nest entrances are often accompanied by a pile of soil excavated from the burrow that may disturb turfgrass.”
