Varroa Treatment Arc — Early Recovery Phase (3–4 May 2026)

This dataset contains acoustic recordings and spectrograms from the early recovery phase following Formic Pro treatment applied to a honey bee colony on 30 April 2026. The files document the colony’s first signs of re‑organisation after the suppression period observed on 1 May. The dataset includes two WAV recordings (3 May morning and 3 May afternoon) and three spectrograms (3 May morning, 3 May afternoon, and 4 May morning). The 4 May morning entry is spectrogram‑only due to an intermittent pickup–preamp connection during this period. These recordings form part of a larger acoustic chronology tracking colony behaviour before, during, and after treatment. They show the early return of harmonic structure, midband coherence, and work‑tone patterns as the colony begins to stabilise.
