We got a report of a booklouse infestation in a buckwheat hull mattress, in Sonora California. The mattress is composed of long, twisted tubes of buckwheat hulls, and it is harboring booklice. See images below.
There is some discussion and debate about whether or not booklice are a problem on hull mattresses, online. See “Are there any problems with insects getting into a hull mattress or pillow?” Despite claims from those who sell these mattresses as not being conducive to booklice survival, these mattresses can indeed support booklice.
The literature shows that booklice like buckwheat, as shown in this paper: Food-selection by the booklouse, Liposcelis bostrychophila Badonnel (Psocoptera : Liposcelididae) . We can assume, from the presence of the booklice, that although this is a hull mattress, there is sufficient residue of the buckwheat to support a population of booklice. July 18, 2017.
A home in Sonora had an interior support post, approximately eight feet tall, made from the truck of an oak tree. This oak wood had the bark removed, and there were large, emergence holes in it. The beetle that did the damage was the oak cordwood borer, Xylotrechus nauticus. Specimen collected by David Katosic, 13 July 2017.
While working in the yard on a hot afternoon, July 9, 2017, a couple of these eye gnats (probably Liohippelates) came after me, so to speak. They were incredibly aggressive, flying all around my face, and landing on me. I was very sweaty. I killed one, and then this second fly came. I went inside, got my bug net and a vial of alcohol, and within a minute of two, this fly was all over me again. When it flew near my ear, I could hear the high pitch of its wings beating (but not as high a pitch as a mosquito). He is preserved in the vial now. Columbia California, 9 July 2017. Thanks to Dr. Lynn Kimsey with the ID.
