At this time of year in temperate climes insect activity should be at it peak. Often, the insects themselves may be elusive, but evidence of their feverish activity is all around. In areas of woodland and scrub the leaves of many tree species, such as birch, oak and aspen are rolled into distinctive cigar shapes. These structures are the work of many different insects that construct these rolls either to hide in or as a nursery for their offspring.
