Data from: Impact of urbanization on abundance and phenology of caterpillars and consequences for breeding in an insectivorous bird
Urbanization can have marked effects on plant and animal populations' phenology, population size, predator-prey interactions and reproductive success. These aspects are rarely studied simultaneously in a single system, and some are rarely investigated, e.g. how insect phenology responds to urban development. Here, we study a tri-trophic system of trees – phytophagous insects (caterpillars) – insectivorous birds (great tits) to assess how urbanization influences i) the phenology of each component of this system, ii) insect abundance and iii) avian reproductive success. We use data from two urban and two forest sites in Hungary, central Europe, collected over four consecutive years. Despite a trend of earlier leaf emergence in urban sites there is no evidence for an earlier peak in caterpillar abundance. Thus, contrary to the frequently stated prediction in the literature, the earlier breeding of urban bird populations is not associated with an earlier peak in caterpillar availability. Despite this the seasonal dynamics of caterpillar biomass exhibited striking differences between habitat types with a single clear peak in forests, and several much smaller peaks in urban sites. Caterpillar biomass was higher in forests than urban areas across the entire sampling period, and between 8.5 and 24 times higher during the first brood's chick-rearing period. This higher biomass was not associated with taller trees in forest sites, or with tree species identity, and occurred despite most of our focal trees being native to the study area. Urban great tits laid smaller clutches, experienced more frequent nestling mortality from starvation, reared fewer offspring to fledging age, and their fledglings had lower body mass. Our study strongly indicates that food limitation is responsible for lower avian reproductive success in cities, which is driven by reduced availability of the preferred nestling diet, i.e. caterpillars, rather than phenological shifts in the timing of peak food availability.

Figure 3 in Size, spines and crochets: defences of luna moth caterpillars against predation by brown anoles
Figure 3. Close-ups of luna moth caterpillars sporting scoli equipped with spines that are effective as defence against anoles. Scoli may deliver an aposematic signal as they can vary in colour from green (freshly molted fourth instar, top left) and black (late fourth instar, bottom left) to blue (freshly molted fifth instar, top right) and red (late fifth instar, bottom right).

Figure 1. Left: the brown anole (Anolis sagrei); right: the green anole (Anolis carolinensis). Both species are common in Florida and exhibit excellent climbing abilities, which allow them to hunt for caterpillars on plants.
Figure 2 in Do caterpillars of Dryas iulia alcionea (Lepidoptera, Nymphalidae) show evidence of adaptive behaviour to avoid predation by ants?
Figure 2. Behaviour and disappearance of larvae of Dryas iulia alcionea after resting site removal (fifth instars do not build resting sites, so they were removed from the leaves for only a few seconds). The bars represent the frequency, for each instar, for the two responses found (reconstruction, white bars; no reconstruction, striped bars). Black bars represent caterpillars that disappeared after the beginning of treatment. Ntotal5382 larvae.
