“…Both sexes of C. irus feed on mature L. perennis flowers and females preferentially oviposit on immature L. perennis inflorescences (Swengel 1996;Thom & Daniels 2017). During oviposition, females typically slowly walk on the immature inflorescence while touching and probing with their antennae and abdomen, often spending several minutes at a time on an individual inflorescence (pers.…”

New advancements in camera trap technology have led to wide-spread use in animal monitoring. In this study we tested whether modern self-contained camera traps could be used to identify small lepidopterans such as the frosted elfin (Callophrys irus). A vast majority of photographed lepidopterans, 76/81 (93.83%), were identifiable to family when moving relatively slowly across the camera’s field of view. Although no C. irus were observed, we were able to identify several species of lepidopterans including those of similar size as C. irus. We find that modern camera traps are adequate to sample small lepidopterans and may open new avenues to survey for small rare species such as C. irus over larger areas than typically possible with small field crews and short flight seasons.

“…Sites in Manitoba that had been intentionally burned approximately three to six years earlier supported relatively higher abundances of Poweshiek skipperlings than did sites with more recent and older burns and sites where grazing took place (Dupont-Morozoff et al 2022). Disturbances such as a cutting actionhayingand prescribed burns may improve the suitability of habitats for butterflies (Swengel 1996;Thom and Daniels 2017) but ought to be compatible with the life history of these same butterflies to reduce mortality (Swengel andSwengel 1999, 2015). Our findings regarding seasonal larval positioning of Poweshiek skipperlings suggest that haying in late summer or fall, when larvae are relatively closer to the ground, instead of in midsummer, when the eggs or larvae are located in the vegetative canopy, may positively influence the vegetative components of habitats without directly displacing or destroying larvae (e.g., grazing for Pieridae; Nippen et al 2021).…”

The Poweshiek skipperling (Oarisma poweshiek) is endemic to the tall grass prairie in North America and is now critically endangered globally. Existing populations are scattered among tall grass prairie remnants. However, the host food plants eaten by Poweshiek skipperling larvae, the vegetative and microclimatic descriptions of immature and adult microhabitats, and O. poweshiek behaviour in Manitoba are unknown. We followed Poweshiek skipperling adults in their natural habitat to locate microhabitats where eggs were laid and to observe larval foraging behaviour and development. We measured vegetative, structural, and microclimatic characteristics of microhabitats used by immatures and documented the host species larvae consumed, their general behaviour (on plants; movement within microhabitats), and their developmental schedules. Larvae ate Andropogon gerardi, Muhlenbergia richardsonis, Sporobolus heterolepis, and Schizachyrium scoparium (all Poaceae) in natural tall grass prairie. Larvae appeared to navigate microhabitats to locate host food plants, alternating between shoots of various species throughout their development. Microhabitats seemed to be more open, with drier microclimates, than areas where eggs were not laid. This improved understanding of larval feeding patterns, adult behaviours, and microhabitat attributes may help local grassland stewards and researchers reduce the list of possible causes of decline and identify potential solutions to recover the Poweshiek skipperling.

“…Butterflies also use volatile chemicals, searching for host plants to lay eggs on to provide their larvae with easily-accessible nearby food. Butterflies’ feeding habits are divided into euryphagy and oligophagy, which could be related to their distinguishing ability to chemical volatiles of hosts, inhabit, and evolve [ 28 , 29 , 30 ]. Cethosia cyane males depend on visual and olfactory cues to distinguish between males and females during courtship [ 26 ].…”

Colour Selection and Olfactory Responses of Papilio demoleus during Foraging and Courtship

Colours and odours are the most important cues for butterflies to localise food and mating partners. We studied the visual and olfactory responses of the widely distributed butterfly Papilio demoleus Linnaeus during foraging and courtship. P. demoleus visited odourless flowers with six colours except green and black, with red as the favourite colour (650–780 nm). Males and females differed in behaviour while visiting flowers. Males were more active than females during foraging. The application of honey water resulted in a significant increase in flower visits by both females and males, and they scarcely visited the apetalous branches with odours. Under natural conditions, four patterns were observed: males chasing males (42.28%), males chasing females (30.56%), females chasing females (13.73%), and females chasing males (13.43%). Males chasing males was the most frequent, probably because males drive away competing con-specific males. When butterflies visited odourless mimics, males chasing females (70.73%) and males chasing males (29.27%) also occurred, indicating that males could accurately distinguish mates using colours only without any chemical cues, and females need chemical cues. The behavioural responses of P. demoleus to floral visits and courtship suggest that colour is the dominant factor during foraging and courtship. We verified the presence of P. demoleus rhodopsin genes, including Rh2, Rh3, Rh4, and Rh5, for long wavelength, blue, and ultraviolet (UV) spectrum recognition, which is consistent with the colour recognition of flowers and wings during visiting flowers and courtship.
