The different varieties of flies in the world are overwhelming, numbering in the thousands, and each one is unique. Generally, we humans are most familiar with flies with synanthropic behaviors, in short, those that have adapted to coexist with our species, being transmitters of diseases or parasites. Other flies are predators of other insects, others feed only on fruit or nectar. There are other species such as those of the Syrphidae family that have the particularity of imitating bees or wasps at the morphological level, which allows them to deceive predators. It is simply a fantastic world, thank you very much for your visit.
