Deep dives
Insect Size Diversity
Insects exhibit an astonishing range of size diversity, varying by a factor of about 5.2 million in body mass. This includes extremely small species like parasitic wasps that can be comparable in size to single-cell organisms, alongside massive beetles that can cover an adult's palm. Such size differences highlight the unique evolutionary adaptations of insects compared to vertebrates, where birds only vary by a factor of 72,000. This diversity in size contributes to our understanding of what constitutes insect life and challenges common misconceptions about their characteristics.
