Death-moth

This is a picture of a Death's-head Hawkmoth, taken from http://en.wikipedia.org/wiki/Image:Acherontia_lachesis.jpg

There is some intersting reading there too. I stole some:

The name Death's-head Hawkmoth usually refers to one of the three species (A. atropos, A. styx and A. lachesis) of moth in the Acherontia genus. Found throughout the Middle East and the Mediterranean region, and increasingly as far north as southern Great Britain due to recently mild British winters, this moth is easily distinguishable by a skull-shaped pattern on its back.
The moth also has numerous other unique features, such as an ability to emit a loud squeak if irritated. The sound is produced by expelling air from its pharynx. It is commonly observed raiding beehives for honey. It is attacked by guard bees at the entrance, but the thick cuticle and resistance to venom allow it to enter the hive. It is able to move about in hives unmolested because it mimics the scent of the bees (Moritz et al., 1991).
