I find Wikipedia a great data base giving information which no other encyclopedia would give.
I do my bit when somebody tries to mutilate (not edit) an article by, for instance, deleting whole paragraphs or links just because he/she does not like it.
Euthrix potatoria, commonly known as the drinker, is an orange-brown moth in the family Lasiocampidae. The species' common and scientific names derive from the larva's supposed drinking of drops of dew. It is found in Europe, most frequently found in marshy places, fens and riversides but may also be seen in drier, grassy terrain. The larva (caterpillar) of this species grows to about 6 cm (2.3 in) in length and is hairy, striped and spotted, with distinctive tufts fore and aft. Caterpillars hibernate while young and resume feeding in the spring, pupating in a cocoon during the summer.
