Family ARCTIID,E (Arc-ti'i-dae). 
The Tiger-moths , or Arctiids (Arc'ti-ids). 
The Arctiidas includes stout-bodied moths, with moder¬ 
ately broad wings, which in the majority of cases are con¬ 
spicuously striped or spotted, suggesting the popular name 
Tiger-moths; some of the species, however, are unspotted. 
A large proportion of 
the species are exceed- 
ingly beautiful ; this 
renders the family a 
favorite one with collec¬ 
tors. As a rule, when 
at rest, the wings are 
folded roof-like upon 
the body. The moths 
fly at night, and are at¬ 
tracted to lights. 
These moths differ 
from the following fam¬ 
ily in having ocelli; 
these are often prominent, at other times they are difficult 
to see on account of the long hairs with which the head is
