Final answer:
The wasp and the orbweaver spider are engaged in a parasitic relationship where wasps lay eggs on spiders, leading to the latter's death. This is different from commensal relationships, where one species benefits without affecting the other.
Step-by-step explanation:
The relationship between a wasp and an orbweaver spider is an example of a parasitic interaction, in which the wasp benefits at the expense of the spider. Female parasitoid wasps are known to lay their eggs on or inside the bodies of spiders, including orbweaver spiders. When the wasp larvae hatch, they feed on the spider, eventually leading to the spider's death. This relationship contrasts with the commensal relationship described in the reference where the southern masked-weaver benefits by making a nest in a tree without affecting the tree. Additionally, there are instances of mutual deception and exploitation in nature, as seen in the case where male wasps are tricked by orchid flowers resembling female wasps which leads to pollination, a symbiotic relationship favorable for the plant.
