5. Achillea Millefolium L. [Class B', Lit. 1, 2, 3, 4, 8, 11, 
12, 14, 17, 18, 24, 287 b, 610 b, &c.] Abundant in the district. 
It is visited chiefly by flies, but great numbers of Microlepi- 
doptera are often to be seen on the heads. Some of these, 
e. g. Simaethis, are very like in colour to the withered flowers 
and are not easily noticed at a little distance. As many as 
seven specimens of this moth have been seen at once on 
a single tuft of flowers. The idea suggested itself that they 
might be there for protection, as often they stayed motionless 
for a long time.
