Focusing restoration efforts on a small number of 'keystone' plant genera can disproportionately support a majority of Lepidoptera species, thereby enhancing overall ecosystem function. This innovation & design research insight is drawn from a 2020 study published in Nature Communications. Using Meta-analysis and data collation, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing or restoring landscapes, prioritize the inclusion of specific 'keystone' plant genera known to support a wide range of Lepidoptera species to achieve greater biodiversity impact.

Key Findings
- 01Plant-Lepidoptera interactions are consistently skewed across ecosystems.
- 02A small percentage of plant genera support the majority of Lepidoptera species.
- 03The critical plant genera for retaining interaction diversity are geographically consistent.
Application
Design takeaway
When designing or restoring landscapes, prioritize the inclusion of specific 'keystone' plant genera known to support a wide range of Lepidoptera species to achieve greater biodiversity impact.
How to apply
When planning a new park, green roof, or ecological restoration project, consult local biodiversity data to identify and prioritize the planting of native 'keystone' plant genera that are known to support a high diversity of local insect pollinators and herbivores.
Project actions
- 01When designing a green space, research which native plants are known to be 'keystone' species for local insect populations.
- 02Consider the role of plants not just for aesthetics but for their ecological function in supporting food webs.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Large-scale data collation across a broad geographic area.
- +Identifies a consistent pattern of skewed interactions.
Limitations
The study's geographical scope is limited to the contiguous US. Local variations in plant-insect relationships might exist.
Reliability & validity
The study's reliability is enhanced by the meta-analysis of published data. Validity is supported by the consistent patterns observed across different ecosystems.
Think critically
How might the concept of 'keystone' species apply to other design contexts beyond ecological restoration, such as in the selection of materials or components in product design?
Design Principles
"Ecological leverage: Invest resources in elements that yield disproportionately large positive impacts on system health and diversity."
This insight is crucial for designers and engineers involved in landscape architecture, urban planning, and ecological restoration. By identifying and prioritizing these keystone species, interventions can achieve greater biodiversity impact with potentially fewer resources, leading to more efficient and effective ecological design outcomes.
What This Means for Your Design
If you want to help lots of butterflies and moths, plant a few specific types of native plants that they really like, because these plants support most of them.
How to use in your project
- 1.Use this research to justify the selection of specific plant species in your design, demonstrating how your choices will support local biodiversity.

Paragraph starter
This design project prioritizes the use of 'keystone' plant genera, identified through research such as Narango et al. (2020), which demonstrate a disproportionately large support for Lepidoptera species. By focusing on these critical plant types, the design aims to maximize biodiversity impact and ecological function within the restored landscape, contributing to a more robust and resilient ecosystem.
