A visitor of note, however, was Acrobasis adventella: a very interesting moth, if only for its name. The genus Acrobasis comes from the word “akron” meaning a point, or a step which is stepped on, a base. The moth is so described because of the horny tooth at the apex of the scape (the basal segment) of the antenna. This moth is sometimes, but less frequently referred to as Trachycera adventella. Trachycera is an all but extinct genus that similarly refers to the rough, raised tufts on the forewings of some moths. Adventella, on the other hand, means 'stranger' and is so named because of its rarity in the region where it was discovered. It is fairly common in England, however.

And with that new visitor the garden count is up to 433 moths!
