We get less of this in autumn compared to summer

Small flying insect that bites and sucks blood

Pad of paper used to write information down

Helmut Ruska set the basis for the __ microscope

To soak food in seasoning before cooking

Unsettles disturbs

Deep blue; the birthstone of September

Mathematical study of change; small pebble

Coffee extracted in small concentrated amounts

Aerial military combat; no canines to be seen
