Abstract

We compiled and standardised a life-history dataset of the family Pyemotidae to quantify patterns in developmental time, adult longevity, reproductive period and fecundity and to identify the principal environmental drivers that shape them. The dataset contains 263 records from 27 references (1926–2025). Records are highly skewed: Pyemotes zhonghuajia was the single most represented taxon (89 records, 33.9%), followed by records identified only to Pyemotes sp. (70, 26.6%), P. tritici (48, 18.2%) and P. moseri (32, 12.2%). Parameter coverage was biased toward fecundity: 202 records (76.8%) reported fecundity, whereas 55 records (20.9%) reported adult longevity, 52 (19.8%) reported developmental time and 41 (15.6%) reported reproductive period. The total lifespan was reported only for the females of one nominate species (P. zhonghuajia)—about 30.5 days at 32 ℃ to 80 days at 16 ℃. Temporal coverage was concentrated in recent years: 165 records (62.7%) were published during 2016–2025, reflecting an increase in experimental (thermal, density and storage) studies that disproportionately focused on P. zhonghuajia.
