How do you filter records based on Observation fields - for instance host plant?

For instance
https://www.inaturalist.org/observations/136141384
This is one of my observations of honey bee pollinating Avocado flowers. I have to observation fields

  1. Pollinating
  2. Associated host plant as Avocado.
    My question is, if it is possible to now group all observations in a regions with observation field of Avocado? If yes how can this be done?
