Description edit

 
Mounted specimen

Aplocera praeformata has a wingspan of 34–44 mm. The forewings have a gray to blue-gray basic color. They show various bands of dark transverse lines. A red-brown stain extends towards the wing tip. The hind wings are monochrome gray-white without any drawing.

This species is rather similar to Aplocera plagiata.

Biology edit

Adults are on the wing from June to August. [6] This species has one generation a year univoltine. The caterpillars are gray-brown, with a white side line and a dark lower edge. [7] The larvae feed on Hypericum species (St. John's worts), such as Hypericum maculatum and Hypericum perforatum.[8]
