The current study aimed to examine the bionomics of dragonflies and heavy metal accumulation in their bodies and environment (sediments and water) from district Swabi, Khyber Pakhtunkhwa, Pakistan. A total of 1683 dragonflies were collected from May to September, 2018 in 4 tehsils (administrative subdivisions) of district. Orthetrum pruinosum neglectum was the most abundant species followed by O. anceps and O. chrysostigma luzonicum. Highest abundance was observed in July and August corresponding to maximum temperature and rainfall. Dragonflies displayed preferable abundance within agricultural lands and on elevation ranging from 206 to 506 m. Heavy metal analysis of sediments and water samples from 4 tehsils showed significant differences in mean concentrations of Pb, Zn, Cu, and Fe. Abundance among districts was negatively associated with Fe levels in water while the species diversity had a significant positive relationship with Fe in sediments. Accumulation of metals in each body part significantly varied among species. N. tullia tullia and O. anceps specifically demonstrated their tolerance to high concentrations of heavy metals.

目前的研究旨在检查来自巴基斯坦开伯尔 - 普赫图赫瓦省斯瓦比地区的蜻蜓的生物组学及其体内和环境（沉积物和水）中的重金属积累。2018年5月至9月，在全区4个行政区划（行政区划）共采集蜻蜓1683只。Orthetrum pruinosum noticeum是最丰富的物种，其次是O. anceps和O. chrysostigma luzonicum. 在 7 月和 8 月观测到最高丰度，对应于最高温度和降雨量。蜻蜓在农业用地和海拔 206 至 506 m 内显示出较好的丰度。对来自 4 个 tehsil 的沉积物和水样的重金属分析表明，Pb、Zn、Cu 和 Fe 的平均浓度存在显着差异。地区间丰度与水中铁含量呈负相关，而物种多样性与沉积物中铁含量呈显着正相关。身体各部位金属的积累量因物种而异。N. tullia tullia和O. anceps特别证明了它们对高浓度重金属的耐受性。
