In the polymorphic swallowtail butterfly Papilio polytes (Papilionidae), male preference for mimetic and non-mimetic females has been extensively studied. On the other hand, indiscriminate mating attempts on heterospecific butterflies have also been reported in this species, raising questions about mate discriminability. However, due to the inherent rarity of opportunities to observe heterospecific mating attempts, the behavioral background in which such heterospecific interactions occur in the field is unclear, with more observational cases being awaited. In the present study, we report three observations of male P. polytes courting and pairing with heterospecific butterflies, including a male from another family, Nymphalidae. To the best of our knowledge, this is the second report in the world on the pairing between butterflies belonging to different families. Interestingly, the males attempted to mate with freshly eclosed individuals in all three observations. This indicates that active mating attempts by males toward virgin females, a behavior commonly observed in butterflies, may underlie such heterospecific interactions. This also raises questions regarding P. polytes males’ mate discriminability and their role in maintaining female-limited mimetic polymorphism.","PeriodicalId":11745,"journal":{"name":"Entomological Science","volume":"28 3","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ens.12604","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144647044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This species mainly feed on the leaves of Japanese butterbur, Petasites japonicus var. giganteus (Pjg), and also feed on the leaves of giant knotweed, Reynoutria sachalinensis (Rs), wormwood leaves, Artemisia montana, and angular Solomon's seal, Polygonatum odoratum var. maximowiczii. We investigated whether diet mixing with Pjg during the nymphal stage enhances the survival or fecundity of this grasshopper. It was revealed that feeding nutritionally inferior Rs to nymphs extended the adult lifespan. The reproductive speed per lifespan was reduced in females fed the mixed diet, as there was no significant difference in the number of eggs laid per lifespan regardless of the Rs ingested. These results indicate that diet mixing, or the additional Rs intake, had an opposite effect on the life history in the form of higher nymphal mortality and longer adult lifespan of P. sapporensis, altering the reproduction schedule.","PeriodicalId":11745,"journal":{"name":"Entomological Science","volume":"28 3","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144624686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we report on the floral utilization of two sympatric earwig species, Forficula mikado and Anechura harmandi, from summer to autumn on Rebun Island, Hokkaido, Japan. Both the nymphs and adults utilized diverse plant taxa (36 species from 15 families) as either foraging or resting sites. They often utilized flowers of the Asteraceae (15 species) and/or Apiaceae (5 species) as foraging sites, probably because of their easily accessible, exposed pollen. In A. harmandi, both nymphs and adults primarily foraged on asteraceous flowers. However, in F. mikado, nymphs frequently utilized apiaceous flowers, whereas adults primarily exploited asteraceous flowers. This ontogenetic dietary shift may be explained by an innate preference of F. mikado nymphs for apiaceous flowers rather than competition for floral resources between F. mikado and A. harmandi nymphs, because flower-visiting earwigs were not so abundant on the island.","PeriodicalId":11745,"journal":{"name":"Entomological Science","volume":"28 3","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144524926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The species of the group exhibit several morphological and behavioral adaptations, which allow exploiting their host spiders. Here, we describe the external morphology, behavior and natural history of the immature stages of a Darwin wasp Eruga unilabiana Pádua & Sobczak, 2018, a parasitoid of sheet-weaving spiders, Sphecozone sp. and Eurymorion sp. (Linyphiidae). The egg of E. unilabiana is a white mass that is deposited in the anterior region of the spider's abdomen. First stage larvae partially emerge from the egg's chorion. Second stage larvae have a body divided into 13 segments and induce spiders to build a modified web. The third stage larvae have eight pairs of retractable dorsal tubercles with tiny little hooks that help the larvae hang and move on the web threads after the spider dies. These results indicate that the immature stages of E. unilabiana present the same basic morphological and behavioral characteristics already known for the species of the group. However, the last stage larva's strategy of moving first to hang on the web threads before killing the spider is the first record in the group and more studies are needed to assess whether this behavior is adaptive for the wasp.","PeriodicalId":11745,"journal":{"name":"Entomological Science","volume":"27 4","pages":""},"PeriodicalIF":0.7,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142641459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
