Larval aggregation in the heterogeneous (F-C) and two types of homogeneous (F-F and C-C) larval environment. (a) Δpl (where Δpl = proportion of larvae from the fungal-infected patch – proportion of larvae from the uninfected patch) as a measure of larval aggregation in the F-C treatment (Δpl = 0: no effect of fungal-infected patches on larval distribution behaviour; Δpl > 0: aggregation of larvae on fungal infected patches; Δpl < 0: larvae avoid fungal colonies). (b) |Δpl| as a measure of the general tendency of Drosophila larvae to aggregate with conspecifics in the heterogeneous environment (F-C) and two types of homogeneous environment (F-F and C-C). Because larval aggregation in the F-C treatment was measured independently of the patch type (see Methods), |Δpl| is larger than Δpl (2a). (F: fungal-infected patches, C: uninfected control patches)
