Once you have a good handle on the Home keys, you can start expanding to the other keys on the keyboard. Use the same repetition exercises to memorize the locations of the other keys. Use the nearest finger to reach the key. If you are keeping your wrists elevated, you will be able to easily strike the keys that are slightly outside of your reach. 6
Image credit Life Cycle of Aquatic Insects, USEPA. Gilbert Rowley illustrates the mayfly life cycle from the egg to the nymph and through the various adult stages (emerger, dun and spinner) that are of interest to flyfishers.
Whiteflies, like many insects, have immature (nymphs) and adult stages. Adults lay eggs randomly, in circles or arcs on the underside of leaves where they spend their entire life cycle. Whitefly nymphs have small, oval bodies and no wings and no apparent legs or antennae.
