Dahlica
triquetrella (Hübner,
1813)  |
| Status
.....A much rarer species in
Nottinghamshire, than both Dahlica lichenella
and Dahlica inconspicuella. There are currently
records from the flood wall at Attenborough NR (Rogers, R.), Newark Railway Station car park and near
the Hucknall Road entrance to Nottingham City Hospital (Pendleton, T.A. and Pendleton,
D.T.). Although the
larvae of all three Dahlicas produce very
similar cases, those of Dahlica triquetrella
are slightly larger (6mm-10mm) and covered with various
insect fragments at the front end. If anything, Dahlica
triquetrella cases are more similar to those of Diplodoma
laichartingella, but less obviously triangular in
cross section. |
