Plants Spawning Invertebrates for Protection

Herbivores are organisms that solely rely on plants as their source of nutrients. Herbivores are a large threat to the plants as it reduces the size of the plants, hindering their ability to acquire resources to survive. Herbivores also restrict growth because many species of plants would focus their energy on developing an adaptation to defend themselves. Herbivores also opens up portals for infectious pathogens to infect the plants. Some plants would develop physical defensive mechanisms such as thorns or trichomes, and others would acquire chemical defenses such as a chemical that makes them taste bad or poisonous.

Some plants, such as corn are able to produce "green leaf volatile compounds" when it's leaves are chewed on. These compounds are a mixture of many chemicals, the most prevalent being terpenoid and phenolic (both of which are very attractive to parasitic wasps). The wasps would fly to the plant being eaten and the wasp would target the threat. The wasp would employ different defensive strategies depending on the species. Some species such as the digger wasps would pick up the host and relocate it elsewhere. Other wasps are more deadly, they would lay eggs in the threat. The eggs would hatch in a day or two and kill the host from within.
