“7 (HE HEATH FRITILLARY-BUTTERFLY. I found the Caterpil- 
Tr lars of this Fly feeding on common Heath in Tottenbam-Wood, about the Middle of 
May, 1745, and they are of the fame fearful Natute as the laft-mentioned. Six or feven of 
them were feeding near each other, I obferved their Manner of eating, which was extremely 
quick, and when they moved it was at a great Rate. I fed them with common Hicath for 
three or four Days; at the End of which fome of them changed into Chryfalis, in which 
State they remained ‘about fourteen Days, and then the Flies came forth. This Buiterjly is 
very common in moft Woods, but its Caterpillar is very rarely found,
