Chemoreceptors play an extremely important role in butterfly life. Outside of helping the butterfly recognize and taste food, they serve to do more.
The sensory systems that butterflies possess are:
The most highly developed senses the butterfly relies on are -
Taste, Smell and Sight.
When seeking food the butterfly places their tarsi, or feet, on possible food sources. Chemo-receptors in the tarsi then relay the food source information to the butterfly brain and simultaneously receptor cells confirm that the food is or is not good. If determined food is good to eat, instinctively the proboscis, or tongue, unrolls ready to take in the nutrients.
When the proboscis is placed on the butterfly food, enzymes are excreted that mix with pollens and turn food into a liquid form. The proboscis then sucks up the necessary nutrients.
Using this part of her legs, the female will steadily tap her legs on the plant or leaves. Eventually releasing juices, the female is able to identify the plant as a good host or not by these juices.

butterfly legs and tarsi and setae. (No sound)

There are many plants with leaves of three, but if they are weeds leave them alone! Poison Ivy, Poison Oak and Atlantic Poison Oak will cause most to break out in a rash if the weeds are touched.

Butterflies are included in the food web. While building your garden it is important to understand what else is going on behind the scenes that can be good or cause problems.
