Info from Licensor: "These are a bunch of Daddy Long Legs on my house. Here in Dillingham, they are known as Dipdoolies. They show up every fall when the weather turns chilly, but I have never seen this many. They would gather under the window sill that is directly above my heater vent. They also gather around door jams. Now the weather is cold enough at night that most of them have disappeared."
