“…Tests at superfamily, family and subfamily taxonomic levels compared the whole BV species phylogeny to published Lepidoptera phylogenies [ 44 , 45 , 46 ]. Tests at the genus level were performed by reconstructing lepidopteran host species phylogenies based on published phylogenies (Noctuidae [ 47 ], Erebidae [ 48 , 49 ], Lasiocampidae [ 50 ], Spodoptera genus [ 51 ]) or when not available on CO1 sequence data extracted from BOLD public database [ 30 ] and compared to the BV species tree simplified by pruning monophyletic clades of species sharing a given host genus down to a single species. Analyses were performed using 25 starts from random maps and heuristic searches for up to 25 generations.…”

The Baculoviridae, a family of insect-specific large DNA viruses, is widely used in both biotechnology and biological control. Its applied value stems from millions of years of evolution influenced by interactions with their hosts and the environment. To understand how ecological interactions have shaped baculovirus diversification, we reconstructed a robust molecular phylogeny using 217 complete genomes and ~580 isolates for which at least one of four lepidopteran core genes was available. We then used a phylogenetic-concept-based approach (mPTP) to delimit 165 baculovirus species, including 38 species derived from new genetic data. Phylogenetic optimization of ecological characters revealed a general pattern of host conservatism punctuated by occasional shifts between closely related hosts and major shifts between lepidopteran superfamilies. Moreover, we found significant phylogenetic conservatism between baculoviruses and the type of plant growth (woody or herbaceous) associated with their insect hosts. In addition, we found that colonization of new ecological niches sometimes led to viral radiation. These macroevolutionary patterns show that besides selection during the infection process, baculovirus diversification was influenced by tritrophic interactions, explained by their persistence on plants and interactions in the midgut during horizontal transmission. This complete eco-evolutionary framework highlights the potential innovations that could still be harnessed from the diversity of baculoviruses.

“…Collective thermoregulatory behaviors are often associated with other traits like dark pigmentation and dense setae that also improve heat capture; cooperative thermoregulation is thus part of an adaptive suite of traits associated with the niche of early spring feeding that is particularly common among the Lasiocampidae. There are close to 2,000 species in the family; it is not known how many of these have gregarious larvae, nor are the phylogenetic relationships between them clear (Regier et al, 2000;Zolotuhin et al, 2012). It has been suggested that gregarious larvae have evolved three separate times within the Lasiocampidae (Regier et al, 2000), but clearly much remains to be understood about the evolution of larval cooperation in this family and the role played by cooperative thermoregulation.…”

Selection Forces Driving Herding of Herbivorous Insect Larvae

Herding behavior is widespread among herbivorous insect larvae across several orders. These larval societies represent one of several different forms of insect sociality that have historically received less attention than the well-known eusocial model but are showing us that social diversity in insects is broader than originally imagined. These alternative forms of sociality often focus attention on the ecology, rather than the genetics, of sociality. Indeed, mutually beneficial cooperation among individuals is increasingly recognized as important relative to relatedness in the evolution of sociality, and I will explore its role in larval insect herds. Larval herds vary in in the complexity of their social behavior but what they have in common includes exhibiting specialized social behaviors that are ineffective in isolated individuals but mutually beneficial in groups. They hence constitute cooperation with direct advantages that doesn’t require kinship between cooperators to be adaptive. Examples include: trail following, head-to-tail processions and other behaviors that keep groups together, huddling tightly to bask, synchronized biting and edge-feeding to overwhelm plant defenses, silk production for shelter building or covering plant trichomes and collective defensive behaviors like head-swaying. Various selective advantages to group living have been suggested and I propose that different benefits are at play in different taxa where herding has evolved independently. Proposed benefits include those relative to selection pressure from abiotic factors (e.g., thermoregulation), to bottom-up pressures from plants or to top-down pressures from natural enemies. The adaptive value of herding cooperation must be understood in the context of the organism’s niche and suite of traits. I propose several such suites in herbivorous larvae that occupy different niches. First, some herds aggregate to thermoregulate collectively, particularly in early spring feeders of the temperate zone. Second, other species aggregate to overwhelm host plant defenses, frequently observed in tropical species. Third, species that feed on toxic plants can aggregate to enhance the warning signal produced by aposematic coloration or stereotyped defensive behaviors. Finally, the combination of traits including gregariousness, conspicuous behavior and warning signals can be favored by a synergy between bottom-up and top-down selective forces. When larvae on toxic plants aggregate to overcome plant defenses, this grouping makes them conspicuous to predators and favors warning signals. I thus conclude that a single explanation is not sufficient for the broad range of herding behaviors that occurs in phylogenetically diverse insect larvae in different environments.

“…Several species have since been considered to belong to Epitrabala (e.g., Pinhey 1975) and published works conflict with the species content of these genera. Hypotrabala was omitted from the tribal classification of Zolotuhin et al (2012) but placed in Selenepherini by Basquin (2023).…”

The Afrotropical lappet moth genus Hypotrabala Holland, 1893 is reviewed utilising specimens housed in the African Natural History Research Trust collections. The synthesis of morphological and DNA analyses has reconciled discrepancies in previous treatments of the genus and Hypotrabala is clearly delimited with implications on the nomenclature and taxonomy. The genus Epitrabala Hering, 1932 syn. n. is synonymised with Hypotrabala resulting in the following changes: Hypotrabala argenteoguttata (Aurivillius, 1909) comb. rev. is revived, H. horridula Tams, 1925 stat. rev. is removed from synonymy with Epitrabala nyassana (Aurivillius, 1909) and two taxa, H. horridula seydeli Tams, 1925 syn. n. and Epitrabala argyrostigma Hering, 1932 syn. n. are synonymised with it. Epitrabala nyassana is transferred to the genus Leptometa (comb. n.) as is Leptometa sanguicincta comb. n. (previously assigned to Hypotrabala), while Hypotrabala odonestioides Berio, 1937 is excluded from Hypotrabala although its generic placement remains uncertain. Based on the structures of the male eighth sternite, Hypotrabala fontainei stat. n. is raised to species status and a new genus Megatrabala gen. n. is described for the striking taxon M. regalis (Tams, 1953) comb. n. Furthermore, 19 new species are described: H. aurantiaca, H. cinereamargo, H. exquisita, H. extenuata, H. giustii, H. indefinita, H. igneata, H. lunda, H. lydiae, H. magnimacula, H. obscura, H. ophioglossa, H. pallens, H. pruinosa, H. retorta, H. smithi, H. tabithae, H. tamsi and H. volynkini spp. n. Certain incongruencies between the results of the barcode analyses and species concepts in this genus and Lasiocampidae more generally are discussed.
