Silver Barred – 2017 (NL)

The Silver Barred (Deltote bankiana) is a small owlet moth that is easy to recognize. The front wings are brown with two silver-coloured parallel diagonal stripes with a few protuberances. It flies both during the day, where I have encountered it so far, and at night. During the day it is easily disturbed and then flies quickly from grass to grass where it will rest with its head downwards. The flight time is in one generation from May to August. Host plant: Purple Moor-grass and Smooth Meadow-grass. Dutch name: Zilverstreep. Frisian name: Sulverstreep.

 

Pretty Marbled – 2017 (NL)

The Pretty Marbled (Deltote deceptoria) resembles the Marbled White Spot (Deltote pygarga), but has both white zones in the zoom field and in the root field. The kidney and eye marks are edged white and can be clearly seen in relation to the black middle band. The rear wing is grey-white with brown edges. It flies in one generation from May to August and the wingspan is 24-26 mm. Host plant: Timothy grass. Dutch name: Bonte marmeruil. Frisian name: Bûnte moarmerûltsje.
