The theme being presented was think twice before you say anything. I think this was the theme because, the grasshopper could not be responsible of getting food, and the ants did not want to give their food. So the theme was think twice before you say anything.
Simile and imagery
Hughes is using simile in this poem to compare what happens when you put off dreams. He compares deferred dreams to things with very strong sensory imagery like drying up "like a raisin in the sun" or stinking "like rotten meat". These details help the reader understand the heavy impact of what will happen if you put your dreams on hold.
