Which statement about temperature and insect development is true?

• A. Insects develop faster at warmer temperatures.
• B. Temperature at the scene are always identical to weather station data.
• C. Temperature has no effect on insect development.
• D. Temperature at the scene may differ from weather station data.

Answer: (D)

Insects develop in a way that is tightly linked to temperature: as the thermal energy available to them increases, their development rate generally speeds up within the species’ viable range. But this isn’t a universal rule; there are upper limits where too-hot conditions slow growth or become lethal, so warmer isn’t always synonymous with faster development for every situation. Temperature experienced at a scene is not guaranteed to match what a weather station records. Microclimates created by sun exposure, shade, indoor vs. outdoor settings, surface materials, humidity, and the time of day can make the scene’s temperature different from nearby weather data. Forensic entomology uses the actual scene temperature history to estimate development stages and time since death, because relying only on weather station data can misrepresent what the insects endured. Thus, the statement that temperature at the scene may differ from weather station data is true.
