The insects that feed on the related plant families Apocynaceae and Asclepiadaceae (here collectively termed "milkweeds") comprise a "component community" of highly specialized, distinctive lineages of species that frequently sequester toxic cardiac glycosides from their host plants for defense against predators and are thus often aposematic, advertising their consequent unpalatability. Such sets of specialized lineages provide opportunities for comparative studies of the rate of adaptation… 

A molecular phylogeny of the African Scarabaeinae (Coleoptera: Scarabaeidae)

The phylogenetic hypothesis of tribal and generic relationships was found to largely concur with that of a recent molecular study done at a global scale, suggesting earliest diverging lineages which are quite distinct from the ones traditionally recognized.

Evolution of Specialization: A Phylogenetic Study of Host Range in the Red Milkweed Beetle (Tetraopes tetraophthalmus)

It is concluded that phylogenetic distance is an integrated measure of phenotypic and ecological attributes of Asclepias species, especially defensive cardenolides, which can be used to explain specialization and constraints on host shifts over evolutionary time.

Evolution of associations between Cymothoe butterflies and their Rinorea host plants in tropical Africa

The results showed that, even though recently diverged species pose a significant problem for effective DNA barcoding, sensitive similarity-based and diagnostic methods can significantly improve identification performance compared with the commonly used tree-based methods.

The combined molecular tree provides a well‐supported estimate of psyllid relationships and shows that there have been several colonizations of the Macaronesian islands but that only one has resulted in a significant radiation.

The Ecology and Evolution of Cycads and Their Symbionts

The gut microbial communities of five insect species feeding on a diversity of tissues of cycads and collected world-wise are surveyed, and a set of core bacteria that is shared amongst cycad herbivores and not found in their non-cycad feeding relatives are discovered.

Molecular Phylogeny of the Small Ermine Moth Genus Yponomeuta (Lepidoptera, Yponomeutidae) in the Palaearctic

The phylogeny of the Palaearctic members of the small ermine moth genus Yponomeuta is reconstructed to provide a solid framework for studies in the evolution of phytophagous insects and their host-plant associations, and to obtain insight into the history of host- plant use and the biogeography of the genus.

A well supported phylogenetic structure is recovered for these early herbivorous hymenopteran clades, with new information regarding the monophyly of Xyelidae, the placement of the superfamily Pamphilioidea as sister to Tenthredinoidea + Unicalcarida, and the interrelationships among the tenthredinoid families Tenthredinidae, Cimbicidae, and Diprionidae.



Host use evolution in Chrysochus milkweed beetles: evidence from behaviour, population genetics and phylogeny

C. cobaltinus thereby has the prerequisites for host race formation on different plants from the original host spectrum, and the sequence‐based phylogeny estimate allows us to reconstruct historical diet evolution in Chrysochus.

By subsampling haplotypes corresponding to particular species, populations, and ecological variants of gibbosus group taxa, it is demonstrated that recovered topologies and genetic distances vary egregiously according to sampling regime.

Phylogenetics and evolution of the aphid genus Uroleucon based on mitochondrial and nuclear DNA sequences

A molecular phylogenetic study was conducted to identify major clades within Uroleucon and to address the cladistic validity of current subgeneric categories, the evolution of host plant associations, the age of origin, and intercontinental movements in this genus.


A molecular phylogenetic study of the 19 specialist or generalist species in the bark beetle genus Dendroctonus, which collectively attack species in four different genera in the conifer family Pinaceae is provided.

Papilio phylogeny based on mitochondrial cytochrome oxidase I and II genes.

These two protein coding genes, particularly COI, show excellent performance in resolving relationships at the level of species and species groups among Papilionidae and are strongly endorsed for future studies aimed at these levels.

Are flightless Galapaganus weevils older than the Galápagos Islands they inhabit?

Based on a mtDNA clock calibrated for arthropods, the initial speciation separating the oldest species, G. galapagoensis on the oldest island, San Cristóbal, from the remaining species in the Galápagos occurred about 7.2 Ma, which exceeds geological ages of the extant emerged islands, although it agrees well with molecular dating of endemic GaláPagos iguanas, geckos and lizards.

Organization of a Plant-Arthropod Association in Simple and Diverse Habitats: The Fauna of Collards (Brassica Oleracea)

The results suggest a new proposition, the resource concentration hypothesis, which states that herbivores are more likely to find and remain on hosts that are growing in dense or nearly pure stands; that the most specialized species frequently attain higher relative densities in simple environments; and that biomass tends to become concentrated in a few species, causing a decrease in the diversity of herbsivores in pure stands.

Insect-Plant Interactions: The Evolution of Component Communities

Evidence that the host associations of specialized herbivorous insects are often phylogenetically very conservative is summarized, and an analysis of host association of eastern North American leaf beetles (Chrysomelidae) is included, because the great majority of these feed on the same plant families as their congeners in other biogeographic regions.

Molecular phylogenetics of sexual and parthenogenetic Timema walking–sticks

COI divergence levels between each of the three parthenogens and their closest sexual relative suggest ancient origins of parthenogenesis, 1.5 to 3 million years ago, that may coincide with the extensive glaciation that formed the North American ice sheets.

Phylogenetics of Cancer crabs (Crustacea: Decapoda: Brachyura).

The phylogeny inferred from maximum likelihood analysis of COI suggested that Cancer originated in the North Pacific in the early Miocene, that the Atlantic species arose from a North Pacific ancestor, and that Cancer crabs invaded the Atlantic from the NorthPacific 6-12 mya.
