Figure 1 from: Guiraud M, Cariou B, Henrion M, Baird E, Gérard M (2021) Higher developmental temperature increases queen production and decreases worker body size in the bumblebee Bombus terrestris. Journal of Hymenoptera Research 88: 39-49. https://doi.org/10.3897/jhr.88.73532

Figure 1 The effect of temperature on the total number of individuals of each caste produced in each colony Colonies A1-A3 and B1-B4 were from session 1, colonies C1-C4 and D1-D4 were from session 2. No significant effect of the session for any caste (p > 0.05). No significant impact of the temperature on the total number of individuals (p = 0.96), neither on the number of males (p = 0.24) or workers (p = 0.34) The number of queens produced was significantly higher at 33°C (p = 0.001).
