Andricus aries | |
Andricus aries is a species of gall-forming wasps, in the genus Andricus.[1][2]
The adults lay their eggs on various species of oak, including Quercus robur, Q. petraea, Q. pubescens and Q. cerris,[3] and the developing larvae cause the trees to create an elongated gall, reminiscent of a ram's horn, hence the epithet aries and the vernacular name "Ram's Horn Gall Wasp".

The species was named by Joseph-Étienne Giraud, in 1859.[4][5] It is found primarily in eastern Europe, but in the 21st century has spread to western Europe,[3] including the United Kingdom. If was first recorded in Berkshire in 1997 and since then has spread all over the southern half of England. Only the asexual generation is known.[6]
