The system data has been assembled solely from photographs, many found on the internet, and covers over 600 species. Some of the photos are such that not all aspects of the larva are visible and thus their data is incomplete. No photographs are available for the remaining species so there is no data for them and data will be added as and when new photographs become available.
In-depth help can be viewed and downloaded as a PDF document.
Leaf-mining larvae are not covered, nor are case-bearing larvae.
Larvae feeding in roots and stems and miners which become free-living are however included where possible.
Larval lengths have been estimated, based on the wing lengths of the adult moths.
Data concerning foodplants has been derived from moth books and thus is not as comprehensive as it could be. Work on data for polyphagous species is in progress.
Links to distribution maps are built into the system.
