Those Unseen Things

At the back of the quarry is an apple tree whose trunk is growing at a 45 degree angle, and it only gets noticed when in flower. If you care to look very closely you might be lucky enough to observe movement in the bark crevices. Flatbugs are aptly named insects whose bodies are very flat so as to enable them to move in the spaces beneath tree bark. There are seven UK species of flatbug, and one of them is thriving in the crevices of the quarry apple tree. Aradus depressus is difficult to see as it is perfectly coloured to blend against bark, but its form is similar to the spear-thistle lacebugs that also thrive in the quarry.
