Laodelphax striatella

This species is listed as Notable A with very few dots on the map at the NBN Atlas. I'm told that several have been found in the Brecks recently but that apart from these there have been very few recent records indeed (two on iRecord: one in Somerset in 2023 and one in Hampshire in 2024). It has been known as Laedelphax striatellus, and the RES key includes it as Delphacodes striatella.

This came to light. I used the RES key to identify it, as well as checking it against both the German books. The RES key has female macropters as being from 3.6mm to 4.3mm but this was only 3.2mm long. This concerned me at first but Biedermann & Niedringhaus have a range of 3.0mm to 4.8mm for macropters. The latter doesn't differentiate between males and females as it does for brachypters.
