To solve the question regarding the butterfly-shaped corolla, let's break it down step by step:

### Step 1: Understand the Question
The question asks for the name of a corolla that is shaped like a butterfly. We need to identify the correct term from the given options.

### Step 2: Define "Corolla"
Corolla refers to the collective term for the petals of a flower. These petals are often colorful and play a crucial role in attracting pollinators.
