I use the iRecord app Moth Survey regularly for my field observations (whether it be a list or a single observation) and find it extremely useful; however, there are a couple of issues I'd like to raise, assuming they are issues and not me missing something.
1. You cannot filter the taxa list to just moths; if moths is the only group ticked, it autolists all taxa possibilities from all groups, not just moths. ideally it should filter just moths irrespective of what other groups are ticked.
2. New Site names are not saved, there is no 'star' icon available as with the casual recording form. The only way I can find to save site names (and view under Menu, Manage Saved) is to create them in the casual form first, then they become available in the Moth Survey.
These remain issues in the latest version v5.4.1.
