Definition

Noun: 1. A carnivorous larva of lacewing flies: An "aphis lion" is the larval stage of insects in the neuropteran families Chrysopidae (green lacewings) and Hemerobiidae (brown lacewings). It is a voracious predator, primarily feeding on soft-bodied insects like aphids, hence its common name.

Usage

• The term is used specifically in entomology and gardening contexts to refer to this beneficial predatory insect larva.
• It is a compound noun where "aphis" refers to its common prey (aphids) and "lion" metaphorically indicates its predatory nature.

Examples

• Noun:
  • The aphis lion is a natural form of pest control in organic gardens.
  • You can often find an aphis lion on the underside of a leaf, consuming aphids.

Advanced Usage

• The term is almost exclusively used in its standard form. In scientific contexts, the more precise terms "lacewing larva" or the family names (e.g., chrysopid larva) might be used.
