The first of these is a barklouse which as its name suggests is associated with bark. These were numerous and as far as I can tell all those I collected were female and at least some were gravid (contained eggs).
|Side view of the barklouse.|
|Dorsal view of the head showing features including the yellow patches at the inner rear edges of the eyes.|
|The 'laciniae', end segments of the maxillae (mouthparts) which have a distinctive shape (a 'pie-crust' edge) and are hardened for curtting and manipulating food.|
|The forewing showing hairs, vein/cell pattern and pale larks on an otherwise brownish wing (the other colours are interference patterns and reflections).|
It certainly seems locally abundant, but this is a species with a British distribution which is not well understood. This shows the value of looking in places such as household timber stores and sheds where overlooked taxa may well be found. More about our firewood inhabitants soon...
