Beetle Collecting & Coleopterology

Collect, preserve, and identify beetles to build a personal reference collection and contribute to biodiversity science.

Beetles comprise 25% of all known animals—over 4,000 species in Britain alone! Collecting and identifying beetles develops deep observational skills. Using techniques like pitfall traps, sweep nets, and log sampling, you'll discover the incredible diversity of these armored insects. Preserve specimens in a collection for reference, contribute observations to scientific databases, and contribute to our understanding of ecosystem health.

How to start

  1. 1
    Learn basic beetle identification using keys and field guides; start with common families.
  2. 2
    Set up pitfall traps (cups buried in soil) in different habitats to passively collect beetles.
  3. 3
    Use a sweep net to catch flying beetles from flowers and vegetation during warm days.
  4. 4
    Turn over logs and stones to find ground-dwelling beetles; replace carefully to avoid damage.
  5. 5
    Preserve specimens in clear plastic boxes with labels (date, location, habitat notes).
  6. 6
    Use dichotomous keys or online resources (e.g., iRecord) to identify to family or species level.

Where to learn more

Plot twists

Ways to spice this up when the basics get boring.

  • Create a visual field guide of local beetle species with photographs and key identification features.
  • Set up pitfall traps across multiple habitats (woodland, grassland, urban) and compare species richness.
  • Investigate beetle phenology: when do different species emerge, peak, and decline seasonally?
  • Document beetle-plant interactions: which beetles specialize on which food plants?
  • Build a preserved reference collection organized by family with detailed locality and date labels.
ADHD notes

Beetles can be collected passively (pitfall traps) or actively; choose based on your energy levels. Identifying specimens to family level is achievable without expertise. Organizing collections provides satisfying structure.

Fun fact

The goliath beetle is one of the heaviest insects on Earth, weighing up to 3.5 kg, with grubs the size of bananas.
