THE BEETLES HANDBOOK

Discover the extraordinary world of beetles and learn how to successfully manage their care from species selection and enclosure setup to feeding, breeding, larval development, health, behavior, and long-term husbandry.
THE BEETLES HANDBOOK is a complete practical guide for beginners, experienced invertebrate keepers, breeders, educators, and beetle enthusiasts. Raphael Hartley combines essential beetle biology with practical husbandry principles to help readers understand different lifestyles, create appropriate environments, raise larvae successfully, and avoid common mistakes throughout the beetle life cycle.
Beetles are among the most diverse animals on Earth, ranging from impressive stag and rhinoceros beetles to colorful flower beetles and many other fascinating species. Their sizes, diets, behaviors, development times, and environmental requirements can vary enormously, making species-specific research an essential part of responsible keeping.
Inside this handbook, you'll discover:
• Beetle anatomy, natural history, behavior, adaptations, and complete life cycle
• How to research and choose beetle species appropriate for your experience and resources
• Selecting healthy captive-bred adults or larvae from responsible sources
• Understanding differences among common beetle groups kept by enthusiasts
• Planning secure enclosures with appropriate space, ventilation, and environmental conditions
• Choosing suitable substrates, hides, climbing materials, and furnishings
• Managing temperature, moisture, humidity, and airflow
• Understanding species-specific feeding requirements for adult beetles
• Food preparation, hygiene, feeding schedules, and preventing spoilage
• Safe handling techniques that reduce falls, injury, escape, and unnecessary stress
• Understanding climbing, burrowing, feeding, defensive, and reproductive behaviors
• Recognizing males and females where reliable characteristics are available
• Preparing adults for responsible breeding and understanding courtship and mating
• Creating suitable egg-laying conditions for breeding females
• Egg development and recognizing newly emerged larvae
• Understanding larval growth stages and the importance of appropriate nutrition
• Selecting suitable larval substrates, including species-appropriate decayed wood or prepared materials
• Monitoring larval development without excessive disturbance
• Preparing for pupation and protecting delicate pupal chambers
• Understanding adult emergence, hardening, maturation, and post-emergence care
• Recognizing mites, mold, injuries, dehydration, developmental problems, and other warning signs
• Preventing overcrowding, aggression, cannibalism, and unsuitable group housing
• Record keeping for feeding, breeding, eggs, larvae, pupation, emergence, and lifespan
• Responsible breeding, population planning, sale, transfer, and long-term keeping
THE BEETLES HANDBOOK emphasizes that there is no single care routine suitable for every beetle. A species that develops in decomposing hardwood may require completely different larval conditions from one associated with soil, compost, or other organic material. Accurate identification and species-specific research should always guide husbandry decisions.
Responsible keeping also means understanding applicable laws and ecological risks. Protected species should not be collected illegally, and captive or non-native beetles should never be released into the environment.
Whether you are preparing for your first beetles, raising larvae, improving a breeding project, or expanding your knowledge of invertebrate husbandry, this handbook provides a dependable foundation.
Choose species wisely, create suitable habitats, understand every stage of development, breed responsibly, and enjoy successful beetle keeping with greater knowledge and confidence.
