Larvae of sawflies

One plant of Salix (? purpurea) with very small narrow pale green leaves almost defoliated by side of canal; about 6-8 larvae found & brought home. (See below!)

Many green & greyish larvae swept off grass (?) &c. by tow-path: one of these brought home as it had 2 (one black, 1 brown) larvae like objects visible beneath its skin, the black one forward, the brown one aft, & as well had a stalked egg [[image]] on pedicel between head & 1st thoracic segment.  Another not brought home had a white projecting mark [[image]] on its back in centre of about 2nd segment behind head.

From the above larvae emerged in 1941 the following: -

13th May  1♀︎ Pteronidia melanopis & 2 other ♀︎♀︎ a few days later, which latter I put out on Salix     
cinerea in garden.
5th June.  A large ♂︎ Mesoleius appeared in pot.

30th May.  A ♂︎ sawfly : Pontania }
9th June  A ♀︎ Pontania, with dark stigma }
14th June  A ♂︎ Pontania, with dark stigma }
16th June  A  ♀ Pontania, with dark stigma }
} Possibly bred from galls on S. purpurea some of which were brought home.

A perfect morning (during which I cut the front hedge) with heavy showers in afternoon & increasing, strong S.W.-W. wind, mild, after a deep depression.  In afternoon drove to Glenasmole & swept in three places above Moore's.  Many insects out in shelter.  Heavy shower at 5 P.M. ended collecting.
