Bagous alismatis (Marsham, 1802)
[Coleoptera : Curculionidae]


Curculio alismatis Marsham, 1802
Hydronomus alismatis (Marsham, 1802).
Bagous alismatis
(Marsham, 1802).


Leaf-miner: The mine starts with a broad corridor. Later a broad blotch, not determined by heavy veins. The mine is full depth and very transparent. The colour in the end is reddish-brown, making mined plants very conspicuous, even from a distance. Frass irregular. Often several larvae in a mine (Bladmineerders van Europa).

Larva: The larvae of beetles have a head capsule and chewing mouthparts with opposable mandibles and lack abdominal legs (see examples).

Described by Scherf (1964a), Urban (1926a), Gosik (2008a) (Bladmineerders van Europa).

Pupa: The pupae of beetles have visible head appendages, wings and legs which lie in sheaths (see examples).

Described by Scherf (1964a), Urban (1926a), Gosik (2008a) (Bladmineerders van Europa).

Adult: The adult is illustrated in the Encyclopedia of Life.
