The Lady Bird Johnson Wildflower Center Fauna Project |
The morning was hot and partly sunny as nine volunteers participated in this week's survey. Here are two of the clues for telling dragonflies and damselflies apart: The former are usually large and tend to rest with wings spread while the latter are smaller and often hold their wings together. Two examples shown below follow these rules, but the Great Spreadwing, a damselfly, is longer than some dragonflies and, as the name implies, holds its wings open.
