How does host selection work for different species of parasitic wasps?

Posted: 11 Jun 2021 02:43 PM PDT

There are thousands of species of parasitic wasps, and they have a diverse range of hosts for which they lay their eggs in, such as caterpillars, spiders, aphids, etc. However, could, for instance, a tarantula hawk wasp be able to lay eggs in a caterpillar, and just prefers targeting spiders, or can it only lay eggs in spiders? Same question applies for other types of parasitic wasps.

What are the exact processes at work that allow Gallium to “poison” other metals like aluminum? I’ve seen several videos of the phenomenon, but want to understand the exact science behind it.

What determines bacterial colony morphology?

What is it that makes some bacterial colonies circular while others filamentous or have ground-glass appearance? I've tried googling the answer to this but I'm not finding anything. Any insight would be greatly appreciated!
