We provide a preliminary account of the bat ectoparasite fauna of Siargao Island, Philippines. Three bat fly species are recorded in this study, representing the genera Brachytarsina Macquart, Eucampsipoda Kolenati, and Megastrebla Maa. There was no published work on Siargao Island bat flies before this study. Thus, this report represents the first published documentation of bat flies in Siargao Island, Philippines.

We summarize the bionomics, distributional information, and habitus photos of all Taiwanese Sympetrum, including S. bacha bacha, S. cordulegaster, S. darwinianum, S. depressiusculum, S. eroticum ardens, S. fonscolombii, S. infuscatum, S. kunckeli, S. nantouensis and S. speciosum. Sympetrum infuscatum is reported from Taiwan for the first time, based on a photo taken on 07 October 2009 in Keelung City. A new record of S. darwinianum found on 09 October 2010 in New Taipei City is reported, representing the second record of the species in Taiwan. Distributional maps of all species and phenological graphs, based on 25 years of citizen science data of 6 selected species (S. cordulegaster, S. depressiusculum, S. eroticum ardens, S. fonscolombii, S. nantouensis and S. speciosum) are also provided.

The pupae of Amphiops were often observed attached horizontally to twigs or floating objects. In the present paper, the author reports a case of pupa adheraena in A. mater Sharp, 1873, which was hanging under a plastic cover under artificial conditions. Furthermore, the potential morphological adaptations for the floating behavior in Amphiops pupae are discussed.

Ischnopsyllidae is a highly specialized family consisting of species exclusively ectoparasitic on bats. The Philippine bat flea fauna currently comprises two subfamilies, three genera and four species. Our study presents the new distribution records from Bohol Island and Balabac Island, as well as the first overview of the natural history and distribution of known ischnopsyllid fleas in the Philippines.

The Erebus Latreille, 1810 populations of Lanyu and Green Island are confirmed to represent a new recorded species, Erebus crepuscularis (Linnaeus, 1758) in the present study. Specimens of both sexes and their genitalia are illustrated and compared with that of the widely distributed Oriental species Erebus ephesperis (Hübner, 1827).

Distributional records of Limnometra femorata Mayr, 1865 in Taiwan were previously confined to Lanyu Island and Green Island. This study reports the first record of the species from Taiwan Island.

The morphology of insect galls often has a species-specific relation to gall-inducers. Therefore, using gall morphotypes as a surrogate of insect species, researchers can preliminarily investigate the gall-inducing insect fauna of an area. The Penghu Islands are the largest offshore islands of Taiwan, but the gall-inducing insect fauna is poorly known. In this study, we selected the widespread Chinese banyan (Ficus microcarpa L.) as the target of our faunistic survey focused on gall-inducing insects. We collected insect galls on F. microcarpa in Magong island, Baisha island and Xiyu island from September 2020 to February 2021. A total of 4 gall morphotypes were newly recorded in the islands. These gall morphotypes were induced by Horidiplosis sp. and an unidentified gall midge (Diptera: Cecidomyiidae, 2 morphotypes), Macrohomotoma gladiata Kuwayama (Hemiptera: Carsidaridae), and Gynaikothrips sp. (Thysanoptera: Phlaeothripidae, 1 morphotype). We infer and discuss the potential taxonomic position of each gall-inducing insect based on given specimens and gall morphotypes. Gall-inducing insects on F. microcarpa in Penghu Islands might naturally disperse from neighboring regions, such as mainland China or Taiwan Island, but there is a possibility that gall-inducing insects were introduced from the southern part of Taiwan Island due to the import of nursery trees for the afforestation project in the 1910s. Further molecular work could help clarify the origin of the gall-inducing insects on F. microcarpa in Penghu Islands.

This study is a supplement to the fauna of Rhipiceridae in Taiwan. In addition to the three documented Sandalus species, we added an undetermined species from Kinmen Island - Rooted in specimen examination, observation, citizen science, and literature, this study aims to provide records of the distribution and phenology of each species. Biological notes based on field observation are provided where possible. The available data indicates that Sandalus sauteri sauteri Emden has two seasonal occurrences: spring to early summer and fall, while other species have a single seasonal occurrence or show no clear pattern due to insufficient data. A number of S. sauteri sauteri were found and collected concurrently in a water tank in southern Taiwan in the early October, 2021. All 24 individuals were male, and may had drowned not long before being collected. It is likely that they were attracted to the water tank by the reflective polarized light while flying in the forest. This new finding suggests an emergence peak of S. sauteri sauteri in early October, which is later than the local cicada seasons and may not overlap with the latter. The phenomenon observed is largely congruent with the behavioral ecology of the Nearctic Sandalus niger Knoch.
