“…For instance, butterflies employ forelegs for smelling or "tasting" substrates (Arikawa, 2001), wasps groom surfaces to scent-mark them (Elmquist et al, 2018), some butterflies carry ductless pheromonal glands not only abdominally but also in their legs (Pinzari et al, 2018), and the female of Phingeris teleius was found to perform "a kind of specific dance, walking around a flower head, drumming with forelegs and often opening its wings" to distribute anti-oviposition pheromones (Sielezniew & Stankiewicz-Fiedurek, 2013).…”

Peculiar behaviour of a female Alaena margaritacea (Eltringham, 1929) (Lepidoptera: Lycaenidae: Poritiinae)

A female Alaena margaritacea was observed using her legs to groom grass blades on a slope, the type locality, near Haenertsburg, Limpopo Province, South Africa. The behaviour was video-recorded. The article describes the behaviour’s peculiarities and stages such as reiterative grooming at blade tips. Using extant literature, it posits two hypotheses for the behaviour’s function: that it involves territorial, sexual scent-marking or that it aims to repel competing feeders such as ants by the putative use of semiochemicals.

“…11), together with the even expression of phototransduction genes across body sections, we speculate that they are distributed more or less evenly within a layer of the larval dermis, rather than in a few spatially restricted specialised cells 38 . Extraocular photoreceptors, resembling light-sensitive phaosome cells in earthworm skin, have been described in the genitalia of swallowtail butterflies and proposed to aid in mate choice and oviposition 43 . Whilst the colour response of blindfolded B. betularia larvae could, in principle, be produced by a highly compartmentalised physiological mechanism, the background matching behaviour suggests the integration of diffuse information from the epidermis, not only about the twig colours but also resemblance to self.…”

Adaptive colour change and background choice behaviour in peppered moth caterpillars is mediated by extraocular photoreception

et al. 2019

Light sensing by tissues distinct from the eye occurs in diverse animal groups, enabling circadian control and phototactic behaviour. Extraocular photoreceptors may also facilitate rapid colour change in cephalopods and lizards, but little is known about the sensory system that mediates slow colour change in arthropods. We previously reported that slow colour change in twig-mimicking caterpillars of the peppered moth ( Biston betularia ) is a response to achromatic and chromatic visual cues. Here we show that the perception of these cues, and the resulting phenotypic responses, does not require ocular vision. Caterpillars with completely obscured ocelli remained capable of enhancing their crypsis by changing colour and choosing to rest on colour-matching twigs. A suite of visual genes, expressed across the larval integument, likely plays a key role in the mechanism. To our knowledge, this is the first evidence that extraocular colour sensing can mediate pigment-based colour change and behaviour in an arthropod.

“…In this section, we briefly review studies on signa, the sclerotized genital structures located in the internal wall of the corpus bursae of many Lepidoptera species (Figs. 12.1b and 12.2), probably the only genital structure of Lepidoptera for which part of the above-mentioned studies have been made (if we exclude the extraordinary genital photoreceptors-four cells-found in the genitalia of several butterfly species-as far as we know, they have not been observed in moths-studied in great detail by Dr. Kentaro Arikawa and collaborators and summarized, for example, in Arikawa 2001). Signa are present in numerous species belonging to most families of Lepidoptera.…”

Cryptic Female Choice in Arthropods

View full text Add to dashboard Cite

The genitalia of male and female Lepidoptera are complex organs, composed of several structures that exhibit great diversity of shapes, sizes, and positions, suggesting that they have evolved in a relatively rapid and divergent way. In this chapter, we explore the selective pressures responsible for the evolution of genital morphology in the Lepidoptera, emphasizing the possible role of post-copulatory intersexual selection (PCIS) mechanisms (cryptic female choice and sexual conflict). Our exploration is in great extent speculative because knowledge on the functional morphology of genitalia in this group is limited. We start by describing the complexity and diversity of genitalia in Lepidoptera, discussing the available information about the role of the different structures in copulation. Then, we discuss possible ways in which PCIS and other types of selective pressures could have influenced the evolution of genitalia by developing illustrative hypothesis for several structures whose function is not well understood. Finally, we describe in detail recent experimental and comparative studies aimed at understanding the function and selective pressures responsible for the evolution of a female genital trait known as signum.
