Bugs and Insects Vocabulary With Pictures

If we study about any bug or insect we should know the term “symbiosis”. If you ever had lice or your cat or dog ever had fleas, you've witnessed symbiosis in action. Similarly most of the insects or bugs posses symbiosis. A symbiotic relationship can have a positive, negative, or neutral effect on the individual species. A symbiotic relationship possessed by any insect or bug may be of following types -

1. mutualism – When both species benefited from the interaction.
2. Parasitism – When one species is benefited and other is harmed.
3. Commensalism – When one is benefitted and other have neutral effect.

Among the bugs and insects which posses symbiosis, mostly are parasites.
Others, which don’t posses symbiosis may be eusocial,Coleoptera, Diptera, Hymenoptera or Lepidoptera.
