The term 'Summer Buzzer' refers to two insects that are commonly found during the summer months: the CICADA (6 letters) and the bumblebee (9 letters). Cicadas are large, flying insects that make a loud buzzing sound. Bumblebees are smaller, fuzzy insects that are known for their distinctive buzzing sound. Both of these insects can be found in gardens, fields, and other outdoor areas during the summer months.
