Senses
Vespid wasps (Vespidae), similar to other insects, have compound eyes that consist of thousands of tiny optical units known as ommatidia, which contain light-sensitive photoreceptor cells.
In biology, the five accepted basic taste qualities are:
- Sweet12
- Salty12
- Sour12
- Bitter12
- Umami312
These fundamental sensations are detected by taste buds located primarily on the tongue, as well as on the palate and in the throat. While these five modalities are recognized in humans, the system evolved to provide animals with essential information regarding the nutrient content and potential dangers of their food. For instance, sweet tastes often signal energy-rich carbohydrates, while bitter tastes frequently serve as a warning for potentially harmful chemicals. Umami, a savory taste, is a response to glutamic acid and its derivatives, such as monosodium glutamate.143
