To solve this question, the user needs to know the characteristics of different insects and their behaviors.

The description in the question suggests that the answer is an insect that is black and yellow and likes to fly around flowers. This is a characteristic of a bumblebee, which is an insect that is often seen flying around flowers collecting nectar.

Now, let's go through each option and explain why it is right or wrong:

A. Wasp: This option is incorrect because wasps are not typically black and yellow. They are more commonly black and yellow or black and white and are not known for their affinity to flowers.

B. Bumblebee: This option is correct. Bumblebees are black and yellow and are often seen flying around flowers, collecting nectar. They are important pollinators for many plants.

C. Moth: This option is incorrect because moths are not typically black and yellow. They come in a variety of colors and patterns, but black and yellow is not a common combination.

D. Writing spider: This option is incorrect because writing spiders are not insects. They are arachnids and have eight legs, while insects have six. Additionally, writing spiders do not fly around flowers and are not black and yellow.

The Answer is: B. Bumblebee
