A classic early-20th‑century entomology issue offering detailed field notes, species comparisons, and colorfully argued ideas on mimicry and life-histories.
This 1920 issue of The Entomologist’s Record and Journal of Variation compiles long-form observations and period notes on butterflies and beetles across Europe. Readers will encounter a continuation of a study on a myrmecophilous lady-bird and its life-history, including discussions of mimicry, habitat choices, and seasonal behavior. The edition also surveys multiple species in the Rhone Valley and adjacent alpine regions, with careful notes on broods, coloration variation, and geographic distribution. It blends descriptive natural history with theoretical reflections on evolution and classification, all grounded in field observation.
What you’ll experience
- In-depth reasoning on why a beetle might live with ants, including discussions of mimicry and natural selection.
- Timed observations about butterfly broods, emergence dates, and how altitude affects presence and color forms.
- Geographic notes that connect habitat patterns to species distribution along the Rhone valley and nearby Alpine areas.
- A companion index detailing dozens of species for quick reference.
Ideal for readers of classic natural history and early 20th‑century entomology, who enjoy careful field notes and the interplay of observation with evolutionary ideas.
