At the top of Ecclesbourne Glen there is a wild rose hedge that has proved to be good habitat for invertebrates. A number of finds over the past year have been new species for the Country Park list. Despite the Bank Holiday Weekend being cold and blustery, fresh leaf growth on the rose hedge was worth searching as it revealed another new species. It was a parasitoid wasp of the Platygastridae family, and not only was it a new species for the Country Park list, it was a new UK species. Until last weekend there were four wasps of the genus Metaclisis on the UK list, there are now five. Metaclisis germanica was described earlier this year as a new species to science, and it had only ever been found in Germany. Identification was made by microscopic examination comparing the wasp to the species description.
