About Caddisflies:

• Caddisflies are moth-like insects that are attracted to lights at night and live near lakes or rivers. 
• Distribution: They are found worldwide, usually in freshwater habitats but sometimes in brackish and tidal waters.
• Features:
  • Adult caddisflies are commonly 3 to 15 millimetres in length. 
  • Generally dull brownish, adult caddisflies resemble moths, with hairy wings and long antennae, but caddisflies do not have the long syphoning mouthparts that butterflies and moths have. 
  • Caddisflies hold their wings tent-like over their bodies when they are not flying.
  • Like stoneflies, mayflies, and dobsonflies, immature caddisflies are aquatic, living in streams and lakes.
  • Caddisfly larvae look similar to the larvae of mayflies, aquatic beetles, and other aquatic insects, but can usually be distinguished by the presence of a “case.”  
  • They feed primarily on plant juices and flower nectar, though a few are predaceous. 
• Importance:
  • Caddisflies are a vital component of aquatic ecosystems. The insects play a crucial role in the food chain.
  • Not only do they serve as a primary food source for various fish species, they also contribute to water purification by filtering algae and other potentially problematic organisms.
