Acentria ephemerella: larva


Acentria ephemerella: larva

full grown larva

Acentria ephemerella: cocoon

pupa in its cocoon


Some of the larvae that hatch live for a short while as borer in the stem or midrib; later they live free. When the shape of the leaf is suitable they live in a folded leaf margin, secured with silk; thy also can use two or three leaves to makes themselves a transportable case. The larva is fully aquatic. Also the pupation is below water, in a flimsy cocoon; after the emergence the exuvium remains in the cocoon. It is no real miner, but the species has been included in Hering’s (1957a) compilation.

host plants

Ceratophyllaceae, Haloragaceae, Hydrocharitaceae, Potamogetonaceae; narrowly polyphagous

Ceratophyllum demersum; Elodea canadensis; Myriophyllum spicatum; Potamogeton lucens, perfoliatus; Stuckenia pectinata.

Mining larvae in September (Hering, 1957a). The larva hibernates, in a hibernaculum in a submerged stem.
