The main difference between insectivorous and symbiotic plants is that the insectivorous plants feed on insects by trapping and digesting them whereas the symbiotic plants evolve close relationships between two species that are mutually beneficial.
Insectivorous plants and symbiotic plants are two types of plants that maintain relationships with other species. Insectivorous plants are a type of partial parasitic plants while symbiotic plants maintain mutualistic, communalistic or parasitic relationships.

What are Insectivorous Plants
Insectivorous plants capture and digest insects in order to supply nitrogen. Nitrogen may not be readily available in either habitat. Carnivorous plants are sometimes called insectivorous. These plants use five main trapping mechanisms. They are:
- Pitfall traps – They trap the prey in a rolled leaf. The bottom portion of the leaf contains a pool of digestive enzymes or bacteria that can digest the prey.
- Flypaper traps – They use a sticky mucilage, which is a thick gluey substance to trap the prey.
- Snap traps – They use rapid leaf movements to capture the prey.
- Bladder traps – They suck in the prey with a bladder, which has an internal vacuum.
- Lobster traps/eel traps – They force the prey to move towards a digestive organ with inward-pointing hairs.
The traps can be either active or passive. The flypaper traps of sundews are active and they bend their tentacles around the prey in order to terrain it during the digestion. The bending is due to the rapid acid growth. Meanwhile, the flypaper trap of the Triphyophyllum is passive and only secrete mucilage.
What are Symbiotic Plants
Symbiotic plants maintain mutualistic, communalistic or parasitic relationships with other species.
- Mutualism – Both partners benefit in mutualism. Mycorrhizal association is an example of tropical mutualism, which occurs between the roots of the plants and fungus.
- Commensalism – Only one partner benefits from the communalistic relationship while the other is not affected. The benefits can be food, shelter or locomotion.
- Parasitism – In parasitism, one partner benefits at the other’s expense. The two types of parasitic plants are total parasite/holoparasite and partial parasite/hemiparasite.
Similarities Between Insectivorous and Symbiotic Plants
- Insectivorous plants and symbiotic plants are two types of plants that maintain relationships with other species.
- Both types of plants have mutual benefits.
Difference Between Insectivorous and Symbiotic Plants
Insectivorous plants are plants that capture and digest insects while symbiotic plants are plants that maintain relationships with other species that can be either beneficial or harmful.
Type of Relationship
Insectivorous plants are parasitic plants while symbiotic plants can be mutualistic, communalistic or parasitic.
Insectivorous plants is a type of symbiotic plant while symbiotic plants maintain relationships for mutualistic benefits.
Pitcher plant (Nepenthes), Sarracenia, sundew (Drosera), Venus fly trap (Dionaea), etc. are examples of insectivorous plants while mycorrhiza, Cuscuta, Rafflesia, etc. are examples of symbiotic plants.
Insectivorous plants depend on insects in order to fulfil their nitrogen requirement while symbiotic plants maintain relationships such as mutualism, commensalism or parasitism. The main difference between insectivorous plants and symbiotic plants is the type of relationship maintained by plants with other organisms.
