Sympetrum flaveolum (Odonata: Libellulidae) a new species record for Iran
راسته Odonata شامل آسیابک‌ها و سنجاقک‌های آبزی و شکارگر است که گاهی به‌عنوان عوامل کنترل بیولوژیک و همچنین شاخص اکولوژیکی کیفیت اکوسیستم‌های آبی مطرح می‌شوند. در این تحقیق طی نمونه‌برداری از منطقه شمال غربی استان اصفهان، گونه Sympetrum flaveolum (Linnaeus) از شهر چادگان، جمع‌آوری و شناسایی شد و سپس به تأیید نگارنده سوم رسید. گونه فوق برای اولین‌بار از ایران گزارش می‌شود.

متن کاملEcological traps for dragonflies in a cemetery: the attraction of Sympetrum species (Odonata: Libellulidae) by horizontally polarizing black gravestones
1. We observed that the dragonfly species Sympetrum flaveolum, S. striolatum, S. sanguineum, S. meridionale and S. danae were attracted by polished black gravestones in a Hungarian cemetery. 2. The insects showed the same behaviour as at water: (i) they perched persistently in the immediate vicinity of the chosen gravestones and defended their perch against other dragonflies; (ii) flying indivi...
متن کاملThe effects of wind speed, competition, and body size on perch height selection in a guild of Libellulidae species (Odonata)
For eleven species of sympatric libellulids, male mean mass was positively correlated with wing aspect ratio, wing loading, and mean perch height. We tested the hypo theses that perch height selection was governed by interspecific competition or biomechanical responses to increased wind speed at higher perches. Although larger odonates might prefer higher perches to offset their increased wing ...
