Data from: The number of days required for egg hatching under five different temperature conditions (15°C, 20°C, 25°C, 30°C and 32°C) in social spider mites

Dataset of the number of days required for egg hatching under five different temperature conditions (15°C, 20°C, 25°C, 30°C and 32°C) in social spider mites: <i>Stigmaeopsis miscanthi</i> mild aggression (ML) form, <i>Stigmaeopsis miscanthi</i> high aggression (HG) form and <i>Stigmaeopsis sabelisi</i>, which were used for analysis in the paper entitled "Phenotypic variability and thermal adaptation in social spider mites: Insights into speciation and local adaptation".
