Summary
No discovery of any parasite ofSphaeroderma rubidium Graell.,Ceratapion carduorum Kirbi, andDepressaria subpropinquella Stain. has been mentioned for France.
However considerable collections ofMymaridae obtained on layings ofS. rubidium, show that parasitism may have a part in the limitation of this species.
The few parasites of larvae and pupae ofC. carduorum obtained do not seem to have any considerable regulating influence.
Although the parasitism of caterpillars ofD. subpropinquella byAngitia is frequent, the latter do not seem to be the essential factor in the evolution of the population of this species.
The caterpillars ofChoreutis bjerkandrella thnb. may be used as a refuge by manyHymenoptera in summer, as a consequence of the scarcety ofMicrolepidoptera at a vulnerable stage.
