LeafByte: A mobile application that measures leaf area and herbivory quickly and accurately

Abstract: In both basic and applied studies, quantification of herbivory on foliage is a key metric in characterizing plant–herbivore interactions, which underpin many ecological, evolutionary and agricultural processes. Current methods of quantifying herbivory are slow or inaccurate. We present LeafByte, a free iOS application for measuring leaf area and herbivory. LeafByte can save data automatically, read and record barcodes, handle both light and dark coloured plant tissue, and be used non‐destructively. We evaluate… Show more

“…Nevertheless, our results are within the same order of magnitude as other studies measuring invertebrate herbivory in the tundra (Barrio et al 2017;Rheubottom et al 2019). Additionally, the method described here bears some similarity to the widely used transparent grid method (Coley 1983, Pearse and Hipp 2009, Henderson and Southwood 2016, which has been shown to accurately measure insect herbivory on plants (Getman-Pickering et al 2020). The current protocol therefore provides a rather fast way of assessing the relative intensity of invertebrate herbivory that can be implemented at different sites.…”

“…The remaining samples were deemed unacceptable due to shape distortion. The Leaf Byte app [64] iOS (iPhone Operating System) version was used for measuring leaf area. tainability 2021, 13, x FOR PEER REVIEW photographs were taken according to the Beckschäfer method [62] a during windless weather and standard overcast condition [63].…”

“…In contrast to WinFOLIA, several leaf phenotyping freeware tools have the added benefit of being mobile applications, enabling enhanced portability relative to flatbed scanner systems. BioLeaf [19] and LeafByte [20] are freely available smartphone applications that can rapidly quantify the proportion of damage to leaves from pests. These apps considerably lower the equipment requirement for imaging leaf tissue and lower the technical learning curve for researchers and breeders that wish to approach pest damage and deterrence quantitatively.…”
