Stink bugs lay their eggs in masses. There are several
species of very small wasps
that take advantage of this by
searching for stink bug egg
masses and laying their own
eggs inside the individual
stink bug eggs. Is this a symbiosis question? What kind and how do you know?

No

Explanation:

The relationship between stink bugs and the small wasps according to the illustration is not a symbiosis one. Rather, it can be considered parasitism because the small wasps benefit while the stink bug is negatively affected.

In symbiotic relationships, both organisms benefit while in relationships that are parasitic, the parasite benefits while the host is negatively affected.

When the small wasps lay their eggs inside stink bug's eggs, they destroy the eggs of the stink bugs to their own advantage. Hence, the stink bug can be considered the host while the small wasps are considered the parasite.
