Bug in Franklin County Massachusetts

[dfishkind]

Found crawling on my wife’s neck in bed this morning. Was very difficult to crush. It didn’t seem flat, but when pinched it just popped back into shape. Had to roll it around between my fingers to get it to die. Is it a bed bug?

That's a deer fly, Lipoptena cervi, a bug introduced from Europe. They are parasitic to deer, elk, and horses. They burrow in the fur and drink blood. They can bite humans, but it is rare.

It could be a sheep ked, Melophagus ovinus, an insect that is commonly found on domestic sheep that often crawl onto humans through contact.

It is a fly in the family Hippoboscidae, also known as "keds" or "louse flies".  They are primarily parasites of birds and livestock, not humans.  Some general information on hosts, biology, life cycle can be found at the link below. I have had them land on me when walking through the woods. Perhaps that's how one ended up in your house.
