CDFA Pest Prevention Plant Regulation Practice Exam

To which order does the white-fringed beetle belong?

1. coleoptera

2. lepidoptera

3. diptera

4. homoptera

The correct answer is: coleoptera

The white-fringed beetle belongs to the order Coleoptera, which is the largest order in the animal kingdom, encompassing all beetles. The characteristics that define this order include the presence of hardened forewings called elytra, which cover a pair of membranous hindwings used for flying. Beetles also exhibit complete metamorphosis, going through distinct life stages: egg, larva, pupa, and adult. Recognizing Coleoptera is essential in pest prevention and plant regulation practices, as many beetles can be significant agricultural pests that affect a wide range of crops. The other orders listed do not include the white-fringed beetle. Lepidoptera includes moths and butterflies, while Diptera encompasses flies and mosquitoes, which have different anatomical and ecological characteristics. Homoptera, which includes groups like aphids and cicadas, is distinct from beetles in its features and life cycle. Thus, understanding the taxonomy and characteristics of these orders is integral for effective pest management.
