We live in northern Wisconsin. My husband was in the lake (it has a mucky bottom) and felt something poke him in his big toe. When I looked at his toe it had a raised blister type mark. It resembled a sting mark with a very pronounced dot of where the bite/sting occured. The toe swelled and he experienced extreme pain. Do you know what type of a bug would live in the muck of a lake and sting? Thanks for your help.
Not to be funny, but it sounds like your husband was bitten by a Toe-Biter or Giant Water Bug.
