“…In conclusion, the results reported here are a reminder that many decades are often needed for the evaluation of basic assumptions that underlie ecological theory, especially when that theory is applied to complex traits such as digestion, development, and host use. A similar study was recently conducted with armored scale insects, with the conclusion that diet breadth and abundance are not linked (Peterson et al 2020). Although Peterson et al (2020) did not detect an overall abundance-diet breadth relationship, it is the case that the most abundant species tended to be extreme specialists.…”

Although Peterson et al (2020) did not detect an overall abundance-diet breadth relationship, it is the case that the most abundant species tended to be extreme specialists. There is clearly much yet to be learned about ecological and dietary specialization, and the observations reported here are made more relevant in the midst of ongoing reports of declining insect abundances from around the world (Salcido et al 2020; Wagner 2020).…”

Some of the most common ecological interactions are between plants and herbivorous insects, and these relationships are central to the study of ecological specialization. We address established assumptions about the positive association between local abundance and dietary specialization using a 17-year dataset on the caterpillars of Ecuador. Our long-term data include standardized plot-based samples as well as general, regional collections, allowing for investigations across spatial scales and using different indices of abundance for 1917 morphospecies of Lepidoptera from 33 families. We find that specialists are locally more abundant than generalists, consistent with a key component of the “jack of all trades, master of none” hypothesis, which has otherwise received poor to mixed support from previous studies that have mostly involved fewer species and shorter time series. Generalists achieve greater prevalence across the landscape, and we find some evidence for geographic variation in the abundance-diet breadth relationship, in particular among elevational bands. Interspecific variation in abundance also had a negative relationship with diet breadth, with specialists having more variable abundances across species. The fact that more specialized species can be both rare and common highlights the ecological complexity of specialization.

“…The first survey was conducted in June 2012 by Geoffrey E. Morse and BBN, and the second in January 2015 by G. E. Morse, Daniel A. Peterson, Hannah Shapiro, and Shannon Trujillo. A full description of the sampling protocol is given in Peterson et al (2020). Briefly, in each survey, investigators sampled all the tree species accessible from the canopy crane, and sampled multiple individuals of the more abundant species.…”

“…Two of the goals of this effort are to test for cryptic diversity within apparently polyphagous species and to test whether a species' local abundance is correlated with its host range. Results of tests of these hypotheses using samples from Panama and Borneo are reported in Peterson et al (2020). Briefly, cryptic diversity is found within some apparently polyphagous species within their native ranges, but some invasive species are truly polyphagous.…”

Four new species of armored scale insect, Clavaspis selvaticasp. nov., Clavaspis virolaesp. nov., Davidsonaspis tovomitaesp. nov., and Rungaspis neotropicalissp. nov., are described and illustrated from Panama. We also transfer two previously described species of Panamanian Aspidiotini to new genera, Hemiberlesia crescentiae (Ferris) comb. nov. and Rungaspis rigida (Ferris) comb. nov., and report the first record of Selenaspidopsis browni Nakahara in Panama. A key to the species of Aspidiotini occurring in Panama is provided.

Host repertoires and changing insect–plant interactions

1. One of the main challenges faced by ecologists today is to understand and predict how species interactions will respond to the current environmental change. It is likely that these changes will have a stronger effect on phylogenetic lineages that depend on intimate and specialised ecological interactions, such as most herbivorous insects. 2. In this review, we highlight the aspects that we consider are fundamental for understanding how species interactions change over time. We start by reviewing terminology and conclude that commonly used terms have undesired connotations with regard to what we know about how hosts are acquired and lost over time. 3. Based on that, we suggest host repertoire as a better term to describe the use of multiple hosts than the host range or diet breadth, both of which fail to capture that host use is often non‐contiguous and tend to emphasise the total number of hosts, while ignoring host identity. 4. Another important issue that we highlight is the differentiation between fundamental and realised host repertoires, where the latter is the set of hosts that are actually used in nature, whereas the first includes all hosts that can potentially be used by the species. We show that the characterisation of the fundamental host repertoire is key to understanding how insect–plant interactions will respond to the ecological opportunities instigated by environmental change.

Nonadaptive host‐use specificity in tropical armored scale insects

Abstract: High species diversity has been attributed to the partitioning of available resources into narrow ecological niches (Hutchinson, 1959). Yet, niche breadth varies greatly between species. Herbivorous insects are classic subjects for the study of this variation (Futuyma &
