Volume Two of the new guide to the study of biodiversity in insects Volume Two of Insect Biodiversity: Science and Society presents an entirely new, companion volume of a comprehensive resource for the most current research on the influence insects have on humankind and on our endangered environment. With contributions from leading researchers and scholars on the topic, the text explores relevant topics including biodiversity in different habitats and regions, taxonomic groups, and perspectives. Volume Two offers coverage of Insect Biodiversity in regional settings, such as the Arctic and Asia, and in particular habitats including crops, caves, and islands. The authors also include information on historical, cultural, technical, and climatic perspectives of Insect Biodiversity. This book explores the wide variety of insect species and their evolutionary relationships. Case studies offer assessments on how Insect Biodiversity can help meet the needs of a rapidly expanding human population, and examine the consequences that an increased loss of insect species will have on the world. This important text: * Offers the most up-to-date information on the important topic of Insect Biodiversity * Explores vital topics such as the impact on Insect Biodiversity through habitat loss and degradation and climate change * With its companion Volume I, presents current information on the biodiversity of all insect orders * Contains reviews of Insect Biodiversity in culture and art, in the fossil record, and in agricultural systems * Includes scientific approaches and methods for the study of Insect Biodiversity The book offers scientists, academics, professionals, and students a guide for a better understanding of the biology and ecology of insects, highlighting the need to sustainably manage ecosystems in an ever-changing global environment.

Figure 4.1 Different kinds of insular systems. (a) Oceanic island. The island of Pico in the archipelago of the Azores. This archipelago is one of the best studied for arthropods, as evidenced through the work of Borges and colleagues (Borges 1992, Borges and Brown 1999, Cardoso et al. 2010, Triantis et al. 2010a, Triantis et al. 2010b, Cardoso et al. 2011, Gaspar et al. 2011, Meijer et al. 2011). (b) Cave. View towards entrance from within Algar do Carvão, an ancient lava tube on the Azorean island of Terceira, which harbors a number of endemics, including both spiders and insects (Reboleira et al. 2011). (c) Pleistocene fragment island. Agistri in the Sarconic Islands of Greece. Early on (23–12 million years ago), the Greek islands were all connected in a continuous land mass. Sea transgression (12–5 mya) formed a mid‐Aegean barrier, followed by fragmentation and widening of the Aegean, leading to the Pleistocene, which was characterized by eustatic sea‐level change (Triantis and Mylonas 2009). The long history of connection and isolation has shaped the diversity of arthropods known from the region today (Sfenthourakis and Legakis 2001). (d) Forest fragment. Shown is a “kipuka,” or island of forest surrounded by lava, on the island of Hawaii. Arthropods are often isolated in these fragments and show clear genetic differences among kipukas (Vandergast and Gillespie 2004, Vandergast et al. 2004). (e) Unique habitat islands. Mono Lake is an example of a unique habitat – a saline lake – that is isolated from similar such habitats. It harbors distinct assemblages of organisms, particularly notable being the brine shrimps and alkali flies (Herbst 1999). Other habitat types that hold unique assemblages of arthropods include sand dunes (Van Dam and Matzke 2016) and vernal or desert pools (Ward and Blaustein 1994). (f) Recent fragment islands. Barro Colorado island, in Gatun Lake of Panama, was formed by flooding of the Chagres River in the creation of the Panama Canal (Leigh 2009). As a result, species numbers declined through relaxation of the supersaturated insular biota as it returns to equilibrium. A similar phenomenon has been documented for oaks, which act as islands for leaf‐mining insects (Opler 1974). (g) Sky islands. The American Madrean sky islands of southeastern Arizona and New Mexico have served to isolate many arthropods on the mountain summits. Particularly well known are the jumping spiders in the

Habronattus pugillis

complex (Masta 2000), scorpions (Hughes 2011), and beetles (Smith and Farrell 2005, Ober and Connolly 2015). All photographs by George K. Roderick, used with permission. (

Figure 5.1 Species richness describes the number of different species present, irrespective of abundance, with low species richness (a) characterized by few species, and high species richness (b) characterized by many species. Species evenness describes the relative abundances of species in an assemblage, with low evenness (c) characterized by relatively more of particular species than others, and high evenness (d) characterized by relatively even abundances of the species present. Here we illustrate how, even when the number of individuals in an assemblage is held constant, levels of species richness and evenness can vary dramatically. Original figure by author.

Figure 5.2 Temporal and spatial complementarity. (a–c) Temporal complementarity is the mechanism by which a lepidopteran corn pest (

Helicoverpa zea

) is most effectively controlled (Pfannenstiel and Yeargan 2002). During the day, a lady beetle is an effective predator of the moth eggs (a); at night, a predatory bug is an effective egg predator (b). Predation is maximized through the combined effects of two natural enemies; only with both enemies present are the moths deprived of a daily (temporal) refuge from predation (c). (d–f) On collard plants, spatial complementarity among predator species leads to effective control of pest aphids only when multiple predator species co‐occur (Straub and Snyder 2008). This level of control is because some predator species forage mostly on leaf edges (d), while other predator species access aphids at the center of leaves (e). Only with a diverse predator community (f) are all of the spatial refuges of the aphids removed. Original figure by author.

Figure 5.3 Two extremes of land‐use intensification. (a) Monoculture landscape growing leafy greens in the Central Valley in California, USA. This type of large‐scale farming relies heavily on synthetic fertilizers, tillage, and chemical control of pest insects. There is an obvious dearth of resources that might benefit insects. (b) Highly diversified farm with multiple crops, orchards, livestock, and weedy field edges, all of which can contribute to a healthier, more diversified insect community. Original figure by author.

Figure 8.4 Mating sequence of

Zorotypus impolitus

(from fig. 1 of Dallai et al. 2013, by permission). After preliminary courtship (a), a spermatophore is attached (b,c). The male makes additional movements (d–f), and the female bends her body to acquire the spermatophore (g–i). The male then goes behind the female (j), repeats various movements (k,l), moves under the female (m), bends his body (n), and eventually positions himself behind the female (o).

Figure 9.2 Female (length 1.7 cm) and male

Antipaluria urichi

(Clothodidae) from a laboratory culture at Santa Clara University. The male displays typical traits for the order (wings, large eyes, and long antennae) compared with the female, which is nymph‐like in form, a characteristic of all species of Embiodea. Dead oak leaves serve as substrate for their silk spinning, but in nature they live on tree bark and other vertical surfaces that support their food resources: lichens and epiphytic algae.

Figure 9.5 Female of

Antipaluria urichi

(Clothodidae) in a typical posture guarding her egg mass, hidden by thick silk and stalked by a scelionid egg parasitoid, ubiquitous in colonies in their native Trinidad. The thick coating on the egg mass protects the eggs from the parasitoid, which has to spend time digging through to reach the eggs, giving the egg‐guarding female time to detect and repel the wasp (Edgerly 1987a). The webspinner's middle legs are held upward and hooked into the silk covering of the domicile. Webspinners hold their middle legs thusly even when traveling. Artwork by Edward C. Rooks.

Figure 9.6 An adult female of

Macrembia

sp. from Zambia, showing bright colors thought to mimic staphylinid beetles also found in their habitat. Their especially robust silk ejectors are visible on the ventral surface of the front basal tarsus. The silk is unusually wispy for webspinners, which more typically spin silk into cloth‐like coverings. Photograph by author.

Figure 20.2 Phylogenetic distribution of polymorphisms, genetic systems, and known primary endosymbiont taxa. The tree is adapted from Vea and Grimaldi (2016). It is a time‐scaled Bayesian estimate based on multilocus DNA sequence data. The axis gives times before the present in millions of years. Many of these phylogenetic relationships have little support, and at least one is unlikely, namely the sister relationship between Pityococcidae and a clade composed of the Gondwanan Eriococcidae, Conchaspidae, Phoenicococcidae, and Diaspididae. Also, the Eriococcidae are not monophyletic. Rather, they are composed of three separate clades first recognized by Cook and Gullan (2004): the Gondwanan clade, the acanthococcid clade, and the BSE (Beesoniidae, Stictococcidae, Eriococcidae

sensu stricto

) clade. Exemplars of Aleyrodoidea and Psylloidea were not included in the Vea and Grimaldi (2016) data set. These have been appended to the tree with a dashed branch to indicate the uncertainty in their relationships and ages. Polymorphisms: triangle, monomorphic; plus sign, polymorphic; circle, sexually dimorphic. Genetic systems: nothing, unknown; circle, XX–XO; x, thelytoky; diamond, arrhenotoky; triangle, paternal genome elimination; inverted triangle, hermaphroditism; x in box, diploid arrhenotoky; plus sign, 2n–2n. Endosymbionts: filled circles, present; empty circles, absent or unknown. The first two columns represent classes of Proteobacteria, and Flavo. is an abbreviation for the class Flavobacteriia (phylum Bacteroidetes). Original by author.
