Data set development for this project was supported by the Global Biodiversity Information Facility (GBIF), the South African Biodiversity Information Facility (SABIF), and especially by the JRS Biodiversity Foundation, Seattle, USA, who are gratefully acknowledged.

All the persons and institutions mentioned above are sincerely thanked for their contributions to the Lacewing project, and museum curators for access to collections of Neuropterida under their care.

I am particularly indebted to my colleague, Brian Kenyon (Johannesburg) for years of collaboration in the design and implementation of the relational databases that underpin this project and for his exceptional skills as a programmer and insight into what is required of biological databases.

We thank Yongyan Liu for technical implementation of the project.

General in-kind support for Lacewing Digital Library projects has been provided over the years by the Department of Entomology of Texas A&M University, Texas A&M AgriLife Research, and the Texas A&M Libraries.
