    These insects use their eyes for both day and night vision, which is used for prey capture and flight when searching for new habitats. [5] Notonecta glauca, like other insects, have a compound eye. Specifically, their eye is an acone-type with corneal structure, which helps them create a sharp image when both in the water and in the air.

    Some insect larvae, e.g., caterpillars, have a different type of simple eye known as stemmata. These eyes usually provide only a rough image, but (as in sawfly larvae) they can possess resolving powers of 4 degrees of arc, be polarization sensitive and capable of increasing their absolute sensitivity at night by a factor of 1,000 or more.

  9. Infrared vision - Wikipedia

    en.wikipedia.org/wiki/Infrared_vision

    Infrared vision is the capability of biological or artificial systems to detect infrared radiation. The terms thermal vision and thermal imaging [ 1 ] [ 2 ] are also commonly used in this context since infrared emissions from a body are directly related to their temperature: hotter objects emit more energy in the infrared spectrum than colder ones.
