“…The black swallowtail, B. polydamas (Lepidoptera: Papilionidae: Troidini), is the only swallowtail species found in Chile. It is distributed from the hyperarid Atacama Desert to Mediterranean‐climate regions of Chile (Peña & Ugarte, 1996; Benyamini et al ., 2014), occurring only where its host plants ( Aristolochia spp., Aristolochiaceae) are available (Saldivia & Faúndez, 2015; Rios et al ., 2016). During spring and early summer females oviposit egg clusters on young –and soft– leaves of Aristolochia plants (Pinto et al ., 2009b), which are summer‐deciduous scrambling herbs.…”

1. Group living in caterpillars may enhance individual performance due to sharing of costs associated with individual tasks when dealing with biotic or abiotic ecological factors. 2. In the gregarious caterpillar Battus polydamas archidamas (Papilionidae) egg clusters and caterpillar groups vary in size. We hypothesized that individual survival would be higher in larger groups and that group living would enhance individual performance: shorter development time and/or reduced frequency of (presumably costly) defensive reactions in larvae and larger adult size. We also tested whether the group size conferring the highest survival to laboratory-reared caterpillars matched the most frequent egg clutch size in the field. 3. We collected egg clutches in the field and reared caterpillars in groups of 1, 6, 10, and 14 individuals. We quantified larval survival and stage duration as well as adult mass under laboratory conditions, excluding natural enemies. We also recorded the frequency of larval defensive reactions (thrashing and osmeterium display) against a tactile stimulus of first-instar larvae. 4. Group living enhanced caterpillar survival, particularly during the first instars, when caterpillars are 100% gregarious. Groups of intermediate size reduced larval development time but group living did not affect adult mass. Individual caterpillars in groups showed defensive reactions less frequently than solitary individuals, revealing a cost-saving feature of gregariousness for this swallowtail species. The most frequent clutch size in the field (9-10 eggs) did not match the larval group with highest survival (14 individuals), but did match the group with shortest development time.

Group living in gregarious caterpillars may shorten the larval stage, which is thought to reduce predation exposure. In the gregarious caterpillar Battus polydamas archidamas (Papilionidae) we addressed the effects of simulated predation threat on the duration of the larval stage in solitary and gregarious caterpillars. We further evaluated the consequences of group rearing and predation stimuli for pupal mass. We reared caterpillars singly and in groups of ten individuals. Caterpillars were subjected to simulated predation threats (prodding with a paintbrush) and control larvae were untouched. We determined larval stage duration and pupal mass. We also recorded in solitary and gregarious caterpillars the proportion of individuals reacting to predation threats with distinct behavioural responses. Caterpillars in the group completed larval development earlier than solitary caterpillars. This pattern of accelerated development was already evident in the first instar. Simulated predation reduced the duration of both the entire larval stage and the first instar, but only for caterpillars in the group. Pupal mass was not affected by the predation treatment in either solitary or gregarious caterpillars. Solitary caterpillars showed thrashing and osmeterium display + thrashing more frequently than gregarious caterpillars, while individuals in the group reacted with osmeterium display to a greater extent. Accelerated larval development in response to predation risk has been predicted by theoretical models, but–to our knowledge–this is the first report on gregarious caterpillars. This putative adaptive response did not entail a fitness cost in terms of pupal mass.

“…The nutritional value of diet for animals varies according to the amount of nutrients in the diet and the amount of secondary metabolites of diet (Simpson & Raubenheimer, 2001). Food quality affects the growth (Joern & Behmer, 1997;Prasad & Mukhopadhyay, 2015, Rios et al, 2016, survival, reproductive success and immunity (Yang & Joern, 1994;Ponton et al, 2011) of animals. If the diet does not meet the needs of the organism, it is considered to be an unbalanced diet.…”
