Habitats and plans for monitoring in summer 2013

Russia wins 5-1
The first generation of Borearctia menetriesii offspring has now come to end of its life cycle. Out of some one hundred caterpillars, nineteen have been successfully reared. They produced ten males and nine females. Out of these eleven were reared in Siberia and eight in Finland. When we consider the fact that eighty caterpillars were reared in Finnish conditions and twenty in Siberian, we can calculate that the success rate was much higher in the native range of the species.

Food preference table
This table summarises the observations about food plant preference of the eight breeders. The findings are preliminary and may change. Legend of figures is at bottom.
Indeed, we now believe Larix is an important food plant in the majority of the species range. In Fennoscandia it is not available at the natural habitat, and is replaced by various bog shrubs and herbs.
Preliminary short descriptions of the larval stages
Written by Kimmo Silvonen 15.8.2011. N.B.: The figures pertaining to this article are available at the image gallery about the early stages, see below. We don't have photos of the egg and first instar larva, yet.
Egg
According to Krogerus, the egg is similar to the other Arctiidae: greenish, smooth, nearly spherical.
1st instar larva
Food plants
During this project, in captivity, the caterpillars have been observed to eat the following plant species:
