Lepidoptera 47 1 



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 without a knowledge of 

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

 larvEe are of .the families Nymphahdse, Noctuidse, as- well as others of the 

 Microfrenatffi. 



In 1915 and also in 1916, Mr. Johansen found at 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 4, 1915. 

 Under this date Mr. Johansen's note reads: " Larva 1,0 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 larvae of similar size were collected on July 16. 

 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 onty 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, 1916. Unfor- 

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

 record 71.)
