Butterflies are expedient biodiversity indicators of a healthy environment. As virtuous pollinators, they provide environmental and economic benefits to the agricultural and natural ecosystem. The global loss of the butterfly community, especially in tropical regions, is causing irreparable damage to the ecological landscape. This decline in population is due to habitat degradation, forest succession, loss of symbiotic relations, economic loss due to flooding, forest development plans, low grassland area, global warming, and reforestation. Moreover, the limited information on the molecular resources of butterflies impedes informed conservation planning. The Threatened Species Initiative (TSI) of Korea has started to utilize the benefits of transcriptome‐guided discovery of molecular resources of a few butterfly species, and a few others are in the pipeline. The cataloging of new genes and genetic markers provides the possibility to promote selective utilization of fitness traits for adaptation of the species to the wild and a newer habitat. In this review, we assessed the versatility of whole‐transcriptome information of the Korean threatened butterfly species, such as the lycaenid Protantigius superans and Spindasis takanosis, the Nymphalid butterfly, Fabriciana nerippe, and the Papilionid species Parnassius bremeri. The schema employed under TSI, including the sequencing and downstream bioinformatics pipeline, could act as a reference for research outside of Korean butterflies. While the molecular resources are available to be exploited, their utilization for conservation is still in its infancy. It is important to synthesize these studies together to catalyze further conservation work applying genomics approaches.

“…A growing body of evidence from different geographical regions records the decline of terrestrial insects in general (Eggleton, 2020 ; Van Klink et al, 2020 ; Wagner, 2020 ) and of Lepidoptera in particular (Costache et al, 2021 ; Forister et al, 2011 ; Franzén & Johannesson, 2007 ; Habel et al, 2019 ; Wepprich et al, 2019 ). Butterflies are among the best‐studied insect families, and butterfly monitoring schemes have been established in many countries during the last decades (e.g., Feldmann et al, 2005 ; Henry et al, 2005 ; Stefanescu et al, 2011 ; Van Swaay et al, 1997 , 2008 ), providing great potential for detecting population trends.…”

For many elusive insect species, which are difficult to cover by standard monitoring schemes, innovative survey methods are needed to gain robust data on abundance and population trends. We suggest a monitoring of overwintering larvae for the endangered nymphalid butterfly Limenitis reducta . We tested different removal and capture‐mark‐recapture (CMR) approaches in a field study in the “Alb‐Donau” region, Germany. Classical removal and CMR studies require movement of the organisms under study, but in our approach, we replaced movement of the study organisms by random movement of multiple different surveyors. We tested the validity of the approach by comparing detection frequencies from our field data with simulated detections. Our results indicate that multi‐surveyor removal/CMR techniques are suitable for estimating abundance of overwintering L. reducta larvae. Depending on surveyor experience, the average detection probability ranged between 16% for novices and 35% for experts. The uncertainty of population estimates increased with a decrease in personnel expenditure. Estimated larval densities on a spruce clear‐cut varied between one and three individuals per 100 m 2 , probably related to habitat conditions. We suggest a CMR approach with three to four trained surveyors for the monitoring of L. reducta populations in the overwintering stage. Compared with previous sampling methods, our approach is a powerful tool with clear advantages: long survey period, estimates of the absolute population size accompanied by uncertainty measures, and estimates of overwinter mortality. The proposed method can be adapted and used for several different butterfly species, other insect taxa with specific immobile life stages, and some sessile organisms, for example, elusive plants, fungi, or corals.
