The Silver-washed Fritillary (Female ab. 
New Forest, 5.7.1919, F. \V. F. coll.) 
Larva. When fully grown after the fourth moult, at 
about ten months old, the larva measures 38 mm. long. The 
body tapers slightly at each end. Altogether, there are 
sixty-two rather long, slender spines running in rows down the 
body, four on the first segment, two on the second, four on 
the third and last, and six on each of the remaining segments ; 
the first pair on the anterior segment are the longest and 
project over the head, and curve slightly upwards. The 
general colour of the body is a deep purple-brown, checkered 
and streaked 
with ochreous. 
Along the back 
are two yellow- 
buff stripes, 
separated by a 
fine black line 
and bordered by 
velvety-purple- 
black markings. 
The larva feeds 
at frequent in¬ 
tervals during 
The Silver-washed Fritillary (Hermaphrodite and Tlld 
Dimorphic, New Forest, 1881). With great rap- 
a light, ochreous- 
yellow, tinged 
with green; before 
hatching it is 
ochreous-white, 
with a leaden-grey 
crown, owing to 
the dark head of 
the larva showing 
through the shell. 
Upon hatching, 
the little larva eats 
away part of the 
crown just large 
enough for its 
exit.
