All insects are arthropods.
All arthropods are NOT insects. Spiders and ticks are arthropods, but they are not insects, for example. More info and picturesat the Linn site. Buchanan uses a digitizing tablet and stylus as a painting tool to create the artwork, which he views in progress on his computer monitor. The artist sketches using the tablet in a manner similar to using a pencil, brush or charcoal.
