Insects: Breathing, Sex, and Food

Summary

In this article, we explore the fascinating world of insects through the eyes of entomologist Samm. We learn how insects breathe, how cicadas navigate and mate, and which insects are safe to eat. We also discuss the potential impact of murder hornets on pollinators and the crucial role insects play in pollination.

How do insects breathe?

One Twitter user asked if bugs have lungs, and Samm explained that insects breathe through spiracles on the sides of their bodies. This system allows air to diffuse inside, but it limits their size as oxygen takes time to reach the cells at the center of their bodies.

How do cicadas navigate and mate?

Another user asked how cicadas have sex if they are blind, but Samm clarified that cicadas are not blind and navigate using sound. She also discussed the Masospora fungus, which replaces cicada genitals and causes their backsides to fall off. However, this does not stop them from being hypersexual.

Which insects are safe to eat?

A user asked about the best insects to eat, and while Samm did not provide a direct answer, she explained that bugs are a good source of low-fat, high-protein food. Larger bugs like cicadas and grasshoppers are more filling, but bugs with black and yellow or black and orange coloring should be avoided as they are chemically defended. Crickets and silkworm larvae are commonly eaten and considered edible.

The potential impact of murder hornets

Samm also discussed the concern over murder hornets and their potential impact on pollinators like honeybees if they become established in the US. She explained that murder hornets are a threat because they can wipe out entire beehives in a matter of hours.

The crucial role of insects in pollination

Insects are one of the best means of pollinating plants, with squash bees being particularly effective. Pollination benefits bees by providing protein for their offspring, making it crucial for their survival.

Conclusion

Insects may seem small and insignificant, but they play a crucial role in our ecosystem. From breathing to pollination to food, insects have a significant impact on our lives. As we continue to learn more about these fascinating creatures, we can better appreciate their importance and work towards protecting them.
