Flies are among the most common insects found across the globe, inhabiting a diverse range of environments from urban areas to wild landscapes. Despite their often unwelcome presence, these small creatures play significant roles in ecosystems. Here's an in-depth look at the fascinating world of flies.
1. Diversity and Classification
Flies belong to the order Diptera, which translates to "two wings" in Greek. This order includes over 150,000 species, making it one of the largest groups of insects. Diptera is further divided into two main suborders:
- Brachycera: This group includes larger flies like horseflies and tsetse flies.
- Nematocera: This group consists of smaller, more delicate flies like mosquitoes and midges.
Each species has unique characteristics and ecological roles, contributing to the rich tapestry of life on Earth.
2. Anatomy and Adaptations
Flies are characterized by their single pair of wings, a distinctive feature that sets them apart from other insects. Their hind wings have evolved into small structures called halteres, which aid in balance and flight control.
