to form fine nets. The stickiness of spiders' webs that allows them to adhere to form a 'canvas' is due to droplets of glue suspended on the gossamer threads.

. Small paintings of Philippine in oval shaped frames were sold to tourists by Franz Unterberger (1838–1902) of Innsbruck, an artist who employed other local artists to produce the portraits. These cobweb paintings were exported to England, North America and Germany in significant numbers. In the 19th and early 20th century the cobweb artists of Innsbruck painted landscapes and scenes involving local peasants, as well as military engagements of the wars of independence. The industrial revolution gave many new themes for cobweb artists to paint. From 1920 onwards no new cobweb paintings from the Tyrol have been recorded. Cobweb painting is still occasionally attempted.Cobweb Painter Exhibit

The cobweb canvas

The cobwebs obtained for the early Austrian example came from Agelenidae funnel-web spiders, whose gossamer sheets were collected in the form of a thin canvas, then put under tension to make an oval blank. The canvas can be strengthened by brushing diluted milk onto the web with great care. Considerable attention must be taken to clean the web, removing insect parts, spider droppings, etc. It is noted that people were employed specifically to collect the large amount of cobwebs required for the many canvases.
