Insect herbivores search for their host plants in heterogeneous environments, and the
efficiency of host location may be influenced by plant architecture and abundance. In this
study, we ask how plant and habitat characteristics traditionally thought to attract pollinators
are related to attack rates by floral herbivores. Patterns of floral herbivory by the moth larva
Eupithecia pulchellata were studied in relation to inflorescence size and local plant density
in two years in a natural population of the facultative biennial Digitalis purpurea. Overall …
