the summary of the grasshopper and the cricket

Here is a paragraph which might help you frame the summary of the poem:

The poem here describes two seasons through which continues the poetry of earth. The season of summer is portrayed here through the sound of the grasshopper which is found on grassy areas, in full bloom during summer. The voice of the grasshopper turns from hedge to hedge in this season. Quite opposite is the scene in winter when even in a silent, lonely night one can hear the sound of a cricket's song. Even in the silence of a winter night can be heard the shrill sound of a cricket.
