Extract

The larva of this not uncommon little Pyralid feeds on the seeds of the peppergrass. It has not been described heretofore; the name as given by Packard (American Naturalist, IV., 229) is an error of identification, the species which he represents, copied from Abbot's manuscript drawing, being Enœmia crassinervella, Zell., a Tineid. The true larva of E. pupula lives singly in the heads of the peppergrass in a loose open web, eating the unripe seeds out of the flat pods, forming two holes in each pod on the upper side. The larvæ, though fully exposed, are difficult to see, as their colours harmonize well with the general appearance of the flower heads. The delicate open web is not conspicuous.
