Insect traits

Functional traits of all herbivorous insect species sampled in the study.

• Species: Insect species name (following Fauna Europaea)
• Author: Author and year of species' description (following Fauna Europaea)
• Group: Insect group as used in the analyses
• Body volume: Body volume determined by body length, body width and body height (in mm$^3$)
• Body_shape: Ratio of body length to body width
• Hind_femur_shape: Ratio of hind-femur length to hind-femur width
• Hind_front_leg_ratio: Ratio of front-leg length to hind-leg length (leg length = femur length + tibia length)
• Wing_length_rel: Ratio of wing length to body length
• Leg_length_rel: Ratio of front-leg length to body length (leg length = femur length + tibia length)
• Antenna_length_rel: Ratio antenna length to body length
• Eye_width_rel: Ratio of eye width to head width (Auchenorrhyncha, Heteroptera) / to head height (Orthoptera)
• Feeding_specialization: Insect specialization on food source (m: monophagous, o: oligophagous, p: polyphagous)
• Feeding_tissue: Feeding tissue used for feeding (c: chewers, x: xylem, p: phloem, m: mesophyll, m-p/r: mesophyll as well as phloem and/or reproductive organs, r: reproductive organs, se: ripe seeds)
• Hibernation: Hibernation stage (e: egg, e/n: egg and nymph, n: nymph, a: adult)
• Generations: Number of generations per year (1.5 stands for 1-2 generations per year)
• Moisture_pref_mean: mean of preferred habitat moistures (1: xerophilous, 2: moderately xerophilous, 3: moderately mesohygrophilous, 4: mesohygrophilous, 5: moderately hygrophilous, 6: hygrophilous, 7: moderately hydrophilous, 8: hydrophilous)
• Moisture_pref_range: range of preferred habitat moistures (indicating degree of specialization)
