Brief description

Pulvinaria regalis Canard, 1968 is not generally regarded as a damaging pest. It usually feeds on trees that can easily withstand the sap loss. There have, however, been records of this species causing the death of a host plant, where young and stressed plants seem most at risk.

Pulvinaria regalis Canard, 1968 was first documented together with P. hydrangeae by Nico Schneider and Sandra Tanson in the year 2000 in Luxembourg City (Bonnevoie), Dudelange and Esch-sur-Alzette (Schneider & Tanson 2003: 87).

Currently, 29 records of the horse chestnut scale are accessible through the MNHNL-mdata portal (MNHNL, iNaturalist & GBIF 2019).

Other Pulvinaria taxa

Recently, three other species of this genus, P. floccifera (Westwood), P. hydrangeae (Steinweden) and P. regalis Canard, have migrated to Luxembourg, where they have become established without any problems (Schneider & Tanson 2003: 87).
