| Finding sporocarps may be time consuming, which would contribute to the assumed high degree of polyphagy in fungivorous insects in general. |
| Polyphagy helps to sustain predators when pest density is low in agroecosystems, usually early in the season. |
| Notes on taxonomy and nomenclature: The number of synonyms is a measure of the polyphagy and extensive geographical distribution of this species. |
| Although the extreme polyphagy of this insect is well known, this is the first report of S. littoralis on aquarium plants. |
| However, we still believe that these two measures of host range will reflect the degree of polyphagy of the butterflies and that using more refined measures of host range would only strengthen any patterns found. |
| Considering the invasive behaviour of H. halys in the USA, its polyphagy, and its recent introduction into Switzerland, the EPPO Secretariat decided to add H. halys to the EPPO Alert List. |
