Why do so many flying insects have aquatic larvae?
gpt
Aquatic larvae allow juveniles and adults to exploit different environments and resources. This prevents competition between different life stages of the same species and allows both stages to maximize the resources in their particular environment. Additionally, larvae tend to be much smaller than adults, and the body plans of adults may not be well suited to significantly smaller dimensions, so a different body plan (in this case, one adapted to an aquatic environment) can be advantageous as the larva grows in size. Finally, separating adults from larvae may also serve to protect a population from environmental catastrophe, as terrestrial and aquatic environments are likely to be affected differently from such adverse events.
