Mangrove does have a distinctive moth assemblage, including Chasmina candida (Noctuidae), Thalassodes maipoensis (Geometridae) and Ptyomaxia syntaractis (Pyralidae), which appear to be restricted to mangrove habitat in Hong Kong. There are plenty of other species that are most frequently found in mangrove or reedbed (marsh) habitats, but I'll refrain from listing them all!
I have done very little recording on actual shoreline (either rocky or sandy shores) - but some of the vegetation associated with the highly saline environment within the drift of sea spray appears to have some species only found there. Some of the species recorded by Andrew Hardacre and Mark Sterling from Clear Water Bay and Red Hill, respectively, are not species I see at all in the central N.T.
