Host plants and larval food plants
Host plant is a broad term. It may refer to a larval food plant, a plant used by a sap-feeding insect, a plant visited by adults, or another plant association recorded in a source.
Larval food plant is narrower. It usually means the plant part eaten by the immature insect. This distinction matters when comparing records from different books, checklists, or observation data.
How to browse the records
Start from a category
Use category guides when the plant is only known as a garden tree, fruit tree, vegetable, grass, or broadleaf tree.
Start from an insect
Use static insect pages to review recorded larval host plants and links to plant pages.
Reading Japanese records carefully
Older Japanese records may use historical names, broad plant groups, or source-specific terminology. For research use, check the original source cited on each species or plant page.
