Meloboris insularis is an endemic ichneumonid wasp species of the Azores (Portugal), having been recorded from Faial island. From the historical data, this species could have a very small Extent of Occurrence (16 km2) and Area of Occupancy (16 km2). Despite the location of its description being currently a Nature Reserve (Caldeira do Faial), it is possible that this species has declined in the past as a result of human activity. However, the present situation of this species needs to be further assessed, further research is needed into its population, distribution, threats, ecology, life history and indigenous host species. Conservation/restoration of native habitats, as well as invasive plant species control, could potentially also aid this species' conservation. Based upon the lack of recent data regarding this species population, distribution, threats, ecology and hosts, this species is assessed as Data Deficient (DD).
Meloboris insularis is an endemic ichneumonid wasp species from the island of Faial (Azores, Portugal), having been collected in Caldeira do Faial, currently a Nature Reserve. Based on the data from the 1938 expedition of Frey, Stora and Cedercreutz, the Extent of Occurrence (EOO) would be ca. 16 km² and the Area of Occupancy (AOO) would be ca. 16 km². However, there is no recent information regarding the distribution of this species.
There are no available data on the population size and trend of this species.
Current Population Trend: Unknown
The ecology and traits of this species are unknown. Other ichneumonid wasps from the subfamily Campopleginae, tribe Limnertini are koinobiont endoparasitoids, mainly of Lepidoptera larvae, but for some species also of Coleoptera larvae (Goulet and Huber 1993). This species was collected in a area that is currently a Nature Reserve (Caldeira do Faial).
A lack of information regarding the present status of this species or its unknown indigenous hosts precludes an assessment of potential threats. Nevertheless, this species might be affected by future habitat declines as a consequence of climate change (Ferreira et al., 2016). It can be assumed that despite the area where it was collected being currently a Nature Reserve, habitat degradation caused by past and present human disturbance and land use changes, or by invasive species might also potentially affect or have affected this species or its indigenous hosts.
This species is not protected by regional law. Further research is needed into its population, distribution, threats, ecology and life history as well as into its hosts. Conservation/restoration of native habitats, as well as invasive plant species control, could potentially aid this species' conservation. Historically at least, this species was present in areas that are currently included in the Natural Park of Faial.
