FIGURE 3. Maximum likelihood tree derived from COI sequences of our copepod samples (labeled as P. tortugensis) plus voucher sequences from related copepods in the suborder Ergasilida (see Table 5 for a list). Sequences of copepods confamilial to P. tortugenis (Chondracanthidae) are labelled to species (and shaded blue in the online colour version), and members other taxa are labeled to family (and shaded pink in the colour online version). Support values for bipartitions are indicated, and divergence represented by dark blue scale bar = 3 %.

Data from: Use of an exotic host plant shifts immunity, chemical defense, and viral burden in wild populations of a specialist insect herbivore
<p>Defense against natural enemies constitutes an important driver of herbivore host range evolution in the wild. Populations of the Baltimore checkerspot butterfly, <em>Euphydryas phaeton </em>(Nymphalidae), have recently incorporated an exotic plant, <em>Plantago lanceolata </em>(Plantaginaceae), into their dietary range. To understand the tritrophic consequences of utilizing this exotic host plant, we examined immune performance, chemical defense, and interactions with a natural entomopathogen (Junonia coenia densovirus, <em>Parvoviridae</em>) across wild populations of this specialist herbivore. We measured three immune parameters, sequestration of defensive iridoid glycosides (IGs), and viral infection load in field-collected caterpillars using either <em>P. lanceolata</em> or a native plant, <em>Chelone glabra </em>(Plantaginaceae). We found that larvae using the exotic plant exhibited reduced immunocompetence, compositional differences in IG sequestration, and higher <em>in situ </em>viral burdens compared to those using the native plant. On both host plants, high IG sequestration was associated with reduced hemocyte concentration in the larval hemolymph, providing the first evidence of incompatibility between sequestered chemical defenses and the immune response (i.e., the "vulnerable host" hypothesis) from a field-based study. However, despite this negative relationship between IG sequestration and cellular immunity, caterpillars with greater sequestration harbored lower viral loads. While survival of virus-infected individuals decreased with increasing viral burden, it ultimately did not differ between the exotic and native plants. These results provide evidence that (1) phytochemical sequestration may contribute to defense against pathogens even when immunity is compromised, and (2) herbivore persistence on exotic plant species may be facilitated by sequestration and its role in defense against natural enemies.</p>

How do host-plant use and seasonal life cycle relate to insect body size: A case study on European geometrid moths (Lepidoptera: Geometridae)
<p><span>We used European geometrid moths (> 630 species) as a model group to investigate how life history traits linked to larval host plant use (i.e., diet breadth and host-plant growth form) and seasonal life cycle (i.e., voltinism, overwintering stage, and caterpillar phenology) are related to adult body size in holometabolous insect herbivores. To do so, we applied phylogenetic comparative methods to account for shared evolutionary history among herbivore species. We further categorised larval diet breadth based on the phylogenetic structure of utilised host plant genera. Our results indicate that species associated with woody plants are, on average, larger than herb feeders and increase in size with increasing diet breadth. Obligatorily univoltine species are larger than multivoltine species, and attain larger sizes when their larvae are restricted to the early season. Furthermore, adult body size is significantly smaller in species that overwinter in the pupal stage compared to those that overwinter as egg or caterpillar. In summary, our results indicate that the ecological niche of an holometabolous insect herbivore is strongly interrelated with its size at maturity.</span></p>
