What are two reasons why some moths are not observable in the moth week data set
- Moth week is community based so moths more common in densely populated areas will show up more in the data sets
- Data relies on community involvement so if there is little interest there will be less if a chance for rare moths to be observed
why might the number of moth observations be a better choice to represent sampling effort compared to number of observors that submitted data?
Number of observors does not give us a good idea of the abundance of different moth species being observed when compared to nunber of moths observed
what was the most observed moth species in 2018-2021?
Spongy moth
