Kebun dengan ketersedian air yang cukup dapat dijadikan sebagai habitat bagi Odonata untuk bertahan hidup dan berkembang biak. Penelitian bertujuan mengetahi kelimpahan capung sepanjang Danau Kenanga hingga kebun Fakultas Ilmu Keperawatan, Universitas Indonesia, Depok, Jawa Barat. Jenis penelitian adalah penelitian deskriptif-eksploratif. Penelitian dilakukan dengan metode TTLTK (Tangkap Tandai Lepas Tangkap Kembali). Metode dilaksanakan dengan metode jalur transek, penyusuran jalur yang terdiri dari tiga jalur yaitu jalur kiri, jalur kanan, dan jalur tengah atau jalur air. Teknik analisis data menggunakan rumus indeks kelimpahan spesies dan rumus indeks keanekaragaman Shannon-Wiener. Hasil penelitian menunjukkan indeks kelimpahan dan nilai indeks keanekaragaman capung termasuk kedalam tingkatan rendah. Ditemukan capung sebanyak 52 individu yang terdiri dari 7 spesies. Pantala flavescens adalah spesies yang paling banyak ditemukan dengan jumlah individu sebanyak 41. Didapatkan pula nilai indeks keanekaragaman yakni 0.81649, termasuk kedalam kategori keanekaragaman tingkat rendah karena H’ < 1 diduga karena kondisi lingkungan mengganggu perkembang biakkan capung. Dapat disimpulkan bahwa kelimpahan capung berbanding lurus dengan keanekaragaman capung.

Pantala Flavescens

We conducted an experiment to understand the influence of ecological factors (desiccation, predation threat and density) on two major metamorphic traits, larval period and size at metamorphosis, in the Indian bronze frog,Hylarana temporalis. Tadpoles were reared in groups of 15 (low), 30 (medium) and 60 (high) densities. We created the threat of desiccation by removing 0.5 l water at 10 days intervals until the water quantity reached 0.5 l. Caged dragonfly larvae (Pantala flavescens) provided the predation threat. Results show that each ecological factor independently influenced metamorphic traits but not in an interactive way. Under desiccation threat the tadpoles metamorphosed earlier and at smaller sizes compared to those reared in constant water (at corresponding densities) regardless of presence/absence of predator. In contrast, under predation threat, tadpoles metamorphosed early and at a bigger size than those reared without predator regardless of density of rearing, and desiccation threat. Alternatively, an increase in density of rearing delayed metamorphosis with smaller metamorphic size in constant water and also under threat of desiccation regardless of whether predation threat existed or not. Thus, our study revealed thatH. temporalistadpoles can modify their response to each ecological factor regardless of what other factors operate simultaneously; the threat of desiccation shortens larval period at the cost of growth. Whereas, predator pressure shortens larval period along with increased growth; while greater density increases larval period and slows down growth inH. temporalis.

In this contribution we report the observation of an individual of the migrant dragonfly Pantala flavescens (Fabricius, 1798) found at Montanaro (Piemonte, Italy) on 14 Aug 2019. This represents the first record of the species for mainland Italy and one of the very few available for Western and Central Europe before 2019. We discuss two hypotheses on the origin of this individual integrating available literature with very recent records retrieved from citizen science faunistic platforms.

Behavioral responses of tadpoles of Duttaphrynus melanostictus (Anura: Bufonidae) to cues of starved and fed dragonfly larvae. Tadpoles of Duttaphrynus melanostictus use chemoreception to detect kairomonal cues and excretory metabolites from predatory anuran tadpoles (Hoplobatrachus tigerinus) that consume them. We describe here the behavioral responses of tadpoles of D. melanostictus to predatory dragonfly larvae (Pantala flavescens). The predator’s kairomones (water conditioned by the starved predator) or its diet-derived metabolites released in excreta of predator after consumption of conspecific prey tadpoles were used to simulate predation risk. The tadpoles of D. melanostictus had no behavioral response to predator kairomones. However, the larvae reduced swimming movements and overall time spent in swimming, and had a higher burst speed/swimming velocity in response to water borne cues released from the excreta of predators fed conspecific prey. Thus, just the presence of dragonfly larvae does not elicit defense behaviors in tadpoles of D. melanostictus, but when predation risk is recognized as real (i.e., when tadpoles are exposed to excretory metabolites of predators fed conspecific tadpoles), defense behaviors are activated.
