Natural Enemies Gallery
University of California, Davis, offers an excellent website, Integrated Pest Management, which includes a photo gallery of beneficial insects that act as biological controls against pests. It includes descriptive information and photos. Most entries include photos of the adult bugs, as well as less familiar life stages of eggs, larvae and nymphs. It's useful to be able to recognize the different life stages in your garden so you don't mistakenly destroy beneficials, such as ladybeetle and green lacewing larvae, that are consuming pests for you!

Clever Gardening Technique

Time Your Release of Beneficial Insects in the Garden
Timing and conditions must be just right before releasing beneficials such as lady beetles and praying mantids. Some beneficials are specific about their target and the temperature in which they thrive, so it is essential to match the species with your situation. If temperatures are inhospitable or the food source is insufficient, beneficials may die or abandon your landscape for greener pastures. Even so, releasing ladybeetles or hiding a praying mantid egg case among protective foliage can be a delightful experience for children, encouraging a love of gardening and nature at a young age.
