Population dynamics of an invasive bird parasite, Philornis downsi (Diptera: Muscidae), in the Galapagos Islands
Fig 2
Catch rates of female (filled circles) and male (open circles) P. downsi at the highland and lowland sites, by date traps were emptied.
Vertical bars around points are ± 2SEs of means (only visible when greater than symbol diameter), n = ~30 traps per point. Plus marks (+) delimit consecutive fly generations, estimated with a day-degree based generation time model. Horizontal bars above data scales represent breeding seasons of known hosts.
