Lepidoptera 17 i 



Larvae Collected during the Expedition. 



Various members of the Southern Party of the Canadian Arctic Expedition 

 collected lepidopterous larvae under stones, etc., and these were placed in alcohol. 

 In most instances the specimens were immature, and wit hunt a knowledge of 

 the adults it is not possible to make a report of any value on them. Such 

 larvae are of the families Nymphalidae, Noctuidae, as well as others of the 

 Microfrenatae. 



In 1915 and also in 1916, Mr. Joharfsen found a1 Bernard harbour, North- 

 west Territories, specimens of a small lepidopterous larva feeding commonly 

 in the roots of Pedicularis lanata. The first larva was found on July 1. L915, 

 Under this date Mr. Johansen's note reads: " Larva 10 mm. long, flesh-coloured, 

 with head, neck plate and thoracic feet brown, found in the root of the common 

 red-flowered Pedicularis. The larva had made a tunnel 15 mm. long, down 

 the middle of the root." Other larva? of similar size were collected on July Hi. 

 On July 18, a further examination of plants showed that the larva did not 

 confine its burrows to the roots but that it also tunnelled the stem feeding 

 upon the pith. As a rule only one occurred in a plant. The larva was further 

 met with both in the roots and the stems of Pedicularis on the island forming 

 the north side of the harbour, at Bernard harbour, on June 10, 1910. Unfor- 

 tunately no adults were reared from larva? kept under observation. (Breeding 

 record 71.)
