True or False: Toxorhynchites adults are the largest mosquitos and feed on blood.

Toxorhynchites, often known as the "elephant mosquito," comprises species that are indeed among the larger mosquitoes. However, they are distinct because they do not feed on blood at any stage of their life cycle. Instead, adult Toxorhynchites primarily feed on nectar and other sugary substances. This characteristic sets them apart from most other mosquito species that require blood for egg development.

The confusion with the true nature of Toxorhynchites can lead to misconceptions about their feeding habits and size. While their size might make them appear similar to other mosquitoes that do feed on blood, their ecological role is quite different, as they are not hematophagous (blood-feeding). Therefore, the statement asserting that they feed on blood is incorrect, confirming that the correct answer is that they do not feed on blood at all.
