The diversity and identification of eulophid parasitic
wasps (Hymenoptera: Chalcidoidea: Eulophidae) on
Phyllocnistis labyrinthella (Lepidoptera: Gracillariidae)
from Västerbotten, Sweden
Entomologisk Tidskrift 2012, 133(3): 111-118

Caterpillars of the mining micro-moth Phyllocnistis labyrinthella feed on leaves of aspen
(Populus tremula) and are often parasitized by eulophid wasps. The parasitoids are a
potential important cause of death for the miners. During 2009-2011 we collected mined
leaves from an experimental stand of aspen trees in Västerbotten. Adults emerged from
17-35 percent of the mines and of these every second to third specimen appeared as wasps.
These wasps represented seven species of eulophid parasitoids of which three were new to
Västerbotten: Chrysocharis nitetis (Walker), Cirrospilus diallus (Walker) och Cirrospilus
pictus (Nees). We include an identification key that may be used to identify these eulophid
