Baccharis halimifolia

Baccharis halimifolia

Remarks

One of two species, the other being Bucculatrix ivella, described by Busck (1900) from material reared by Harrison Dyar and named for the supposed host plant, marsh elder (Iva frutescens). Both in fact feed on eastern baccharis (Baccharis halimifolia), which is superfically similar to I. frutescens and often cooccurs with it in salt marshes. Both were found to be highly host-specific in a study of their potential as biocontrols of baccharis in Australia, though marsh elder was not one of the plants tested (Diatloff & Palmer, 1988).
