Euchalcia modestoides Poole, 1989

Host plants:
The larvae feed on Pulmonaria species, besides rarely other Boraginaceae as Cynoglossum or Symphytum.

Habitat:
Euchalcia modestoides inhabits riparian forests, deciduous limestone forests and woodland-near edges of grasslands. The moth is highly bound to open forest with Pulmonaria-stocks.

Life cycle:
The L1 caterpillar overwinters in a cocoon without having fed. The caterpillars are found in April and May. Young caterpillars spin a leaf up at the edges into a bag. In the last instar, they sit on the other hand free on the upper leaf surface. They are often parasitized. Pupation takes place in leaves woven together. The moths fly in June/July, sometimes even in early August.

Endangerment: endangered

Endangerment factors:
Euchalcia modestoides is endangered due to destruction of the Pulmonaria stocks in forest coats: reforestation with spruce, but also maple (dark forest management!), linear forest edges with a hard transition to intensive agricultural land, disposal of timber and sawdust, mowing of forest edges, etc.

Remarks:
This beautiful species occurs in the moutains: Alps and some lower mountains such as the Jurassic mountains (Swabian Alb). Except in Southern and Central European mountains, Euchalcia modestoides is also found in parts of Asia to Mongolia.
