Host plant.
Unknown. In southern Africa adults were feeding on pollen of
Nidorella resedifolia
DC. and
N. auriculata
DC. (
Asteraceae
).
Remarks.
Arge deckerti
is very similar to
A. stuhlmanni
(
Kohl, 1893
)
, both being widely distributed (
Koch 2005
), but
A. deckerti
clearly differs by the entirely yellow costa of the fore wing. In
A. stuhlmanni
the colouration of the costa and subcosta varies from a black apical half to blackish at extreme apex adjacent to the stigma. The lancet of
A. deckerti
is uniformly covered with sensilla, which are absent in
A. stuhlmanni
, and the serrulae are flatter. In lateral view, the penis valve of
A. stuhlmanni
is distinctly broader than in
A. deckerti
(
Koch 2005
)
. Until now
A. stuhlmanni
is not reported for
Ethiopia
.
