What is it about?
Isolated plants attract a disproportionate number of eggs from mobile insects, but this effect becomes less pronounced as resource density (or isolation) is measured at coarser spatial scales

Why is it important?
Even though patchy resources maybe identical in quality, their spatial distribution relative to each other means that the distribution of insect larvae will most likely be non-random. This non-randomness can promote coexistence of competitors using an identical resource base (cf the Aggregation theory of coexistence).
