ENTO 201 – General Entomology | Exam 4 Q&A (60+ Questions) – Orders, Mimicry, Parasitoids, Insect Traits

This document contains over 60 graded and verified questions and answers from Exam 4 of the ENTO 201 2025/2026 course in General Entomology. It provides a detailed review of key insect orders (e.g., Diptera, Hymenoptera, Lepidoptera, Trichoptera, Siphonaptera, Coleoptera, Strepsiptera), along with specific biological, morphological, and ecological traits used to distinguish them. Topics include insect feeding behaviors (e.g., bloodfeeding, herbivory, saprophagy), reproductive systems, metamorphosis types, and evolutionary adaptations like mimicry, aposematism, and haplodiploidy. Additional questions explore parasitoid strategies (idiobionts vs. konobionts, hypoparasitism), medically significant insects (e.g., vectors of sleeping sickness and bubonic plague), and the economic importance of insects such as bees (wax, waggle dance), silkworms (silk), and scarabs (cultural symbolism). Functional anatomy (elytra, halteres, ovipositor) and insect communication are also covered. This resource is ideal for undergraduate students in entomology, biology, zoology, pre-veterinary, environmental sciences, or anyone studying insect science. It supports coursework, lab exam prep, and general review of insect taxonomy and function.
