What are the characteristic features of adult Culex and Culiseta?

• A. Palpi shorter than proboscis and rounded abdomen
• B. Palpi longer than proboscis and rounded abdomen
• C. Proboscis shorter than palpi and pointed abdomen
• D. Palpi and proboscis equal length with elongated abdomen

Answer: (A)

The main idea is how to identify adult mosquitoes at the genus level by simple body features. For Culex and Culiseta, the palps are shorter than the long proboscis, and the abdomen is rounded rather than elongated or pointed. This combination is a reliable diagnostic cue in the field or classroom because other groups often show different patterns, such as palps that are about as long as the proboscis or an abdomen that is more tapered. So, the distinctive trait you look for is short palps relative to a longer proboscis along with a rounded abdomen.
