Philaenus spumarius

Distribution in Belgium

It is present in all the country's ecological regions ( Fig. 1 ). During our field samplings, it was found in all 36 sites. The insects were caught in all environments, on ground vegetation (in meadows, dunes, bogs) as well as on trees and bushes (willows, oaks, birches…) ( Table 4 ).

Adult phenology

The adults can be found from April to November, with higher population from June to September ( Fig. 2 ).

Oviposition, egg winter diapause and voltinism

In the population observed in the laboratory, the eggs were observed at the base of grass blades, protected by a layer of hardened foam. In this univoltine species, the eggs overwinter and need a winter period to overcome diapause.

Immature development under outdoor conditions

It took place between early April and early June ( Fig. 3 ). There are five instars, with spittle protection. Immature development lasted 53 to 63 days, with adults appearing between May 29 and June 6.
