To be a little more specific: Which species only come to forage, which hibernate and which can spend their entire lives on green roofs? Are there any insect groups that are particularly present? Personal observations and studies from Europe are very welcome.
- Diversidad: Sorprendentemente alta, con estudios que muestran hasta 123 taxones diferentes.
- Grupos más comunes: Colémbolos, himenópteros (abejas, avispas, hormigas), dípteros y arañas.
- Uso del hábitat: Forrajeo: Común en polinizadores como abejas. Residencia permanente: Algunas especies completan su ciclo de vida. Hibernación: Posible, aunque menos estudiado.
- Factores influyentes: Positivos: Profundidad del sustrato, diversidad de plantas. Negativos: Altura del edificio.
- Importancia: Contribuyen a la biodiversidad urbana, pero no reemplazan hábitats naturales.
Green roofs support diverse insect communities, influenced by vegetation, roof age, and habitat connectivity. While they attract pollinators and predators, insect abundance is often lower than ground-level habitats due to environmental stress. Increasing plant diversity enhances colonization and ecological function.
Thanks for the answers so far! I translated Carlotas answer:
Diversity: Surprisingly high, with studies showing up to 123 different taxa.
Most common groups: Springtails, Hymenoptera (bees, wasps, ants), Diptera and spiders.
Habitat use: Foraging: Common in pollinators such as bees. Permanent Residence: Some species complete their life cycle. Hibernation: Possible, although less studied.
Influencing factors: Positive: Substrate depth, plant diversity. Negative: Building height.
Importance: Contribute to urban biodiversity, but do not replace natural habitats.
Carlota, do you know which species are known to complete their life cylces on green roofs? Is there a publication about the taxa on green roofs or why do you know that up to 123 different taxa were found?
Puede con gusto responder en español. Muchas gracias!
