1. DISTRIBUTION

Pimpla turionellae [Soortenregister] is a common wasp that can be found across the Netherlands [Waarneming.nl].

 

2. BEHAVIOUR

2.1. ACTIVITY

The species is active from May to October [Fitton et al. 1988].

2.2. DEVELOPMENT

The species has two generations per year [Fitton et al. 1988] and overwinters possibly sometimes as adult [Fitton et al. 1988].

 

3. PARASITIC RELATIONS

P. turionellae is an idiobiont endoparasitoid [Uçkan et al. 2004] on butterflies and moths, hunting on smaller to middle-large pupae, in cocoons and sometimes bare, from the following species occurring in the Netherlands [Soortenregister]:

COSMOPTERIGIDAELimnaecia phragmitella [Fitton et al. 1988]
DEPRESSARIIDAEDepressaria radiella [Fitton et al. 1988]
PYRALIDAEAcrobasis consociella [Fitton et al. 1988]
Ephestia kuehniella [Kansu & Ughacek 1984]
Galleria mellonella [Kansu & Ughacek 1984]
PYRIDAEPieris rapae [Kansu & Ughacek 1984]
TORTRICIDAECydia pomonella [Fitton et al. 1988]
Rhyacionia buoliana [Fitton et al. 1988]
Tortrix viridana [Fitton et al. 1988]

Yponomeuta malinellus [Kolarov 1995],[Kansu & Ughacek 1984]
YPSOLOPHIDAEYpsolopha vittella [Fitton et al. 1988]

The following hosts have been observed in the garden:

Whites
(PYRIDAE)
Small white (Pieris rapae)
Ermine moths
(YPONOMEUTIDAE)
Apple ermine (Yponomeuta malinellus)
