Thread-Waisted Wasp: Harmful or Helpful Insects? 

Thread-waisted wasps (sphecids) are useful insects. The reason

Many thread-waisted wasp species eat caterpillars, beetles, and flies. They seek pests to feed themselves and their larvae, organically controlling populations.  

Natural Pest Control  

Some thread-waisted wasps pollinate flowers by visiting for nectar, though not as well as bees.  

Pollination  

Thread-waisted wasps help degrade organic waste by scavenging dead insects.  

Help decompose  

Thread-waisted wasps are solitary and not hostile towards humans, unlike yellow jackets and hornets. Usually sting when provoked or threatened.  

No aggression

Thread-waisted wasps help balance species and ecological processes in ecosystems.
