“…The body size of Fejervarya cancrivora is larger than Fejervarya limnocharis [2,4]. While the species of frogs that live in rice fields in Japan include Pelophylax nigromaculatus, Pelophylax porosus brevipodus, Hyla (Dryophytes) japonica, Glandirana rugosa, and Fejervarya kawamurai [5].…”

Frogs that live in rice paddy habitats in Indonesia include Fejervarya limnocharis and Fejervarya cancrivora. The species of invertebrate eaten by Fejervarya cancrivora is still little known, so research needs to be done to analyze the species of invertebrate eaten by the frog. Samples of Fejervarya cancrivora frogs were randomly captured at two consecutive nights in the rice fields area of Ciomas sub-district, Bogor Regency and then 20% of the total catch was taken to be anesthetized, the rest was released back to the rice fields. The collection of invertebrates is taken from the gastrointestinal part of the toad. Identification of invertebrate species is carried out on some recognizable body remains of invertebrates. Based on the calculation of the Shannon-Winner Diversity Index, the species of invertebrate found in the female gastro intestinal Fejervarya cancrivora throughout the night has an index value of H* = 0.948, while the invertebrates in the gastrointestinal Fejervarya cancrivora male have an index value of H* = 0.845. Species of invertebrates found in gastrointestinal Fejervarya cancrivora include: Conocephalus longipenis, Panstenon nr. Collaris boucek, Pachydiplossis oryzae, Hydrella philippina, Haplothrips aculeatus, Microvelia douglasi (microvelia), Snellenius (Microplitis) manilae, Cnaphalocrosis medinalis, Oncomelania sp., Chilo supressalis. Euborellia stali (Dohrn), Gonatocerus sp., Dicladispa armigera, Oxyopes javanus, leftover leg crustaceans, Brachymeria lasus, and Nilaparvata lugens.

Paddy fields are classified as wetland environments, and they comprise freshwater ecosystems. They are ecologically important habitats and breeding grounds for many aquatic insects, amphibians, and reptiles. However, paddy field ecosystems are constantly threatened by climate change and the indiscriminate use of pesticides. The metabarcode analysis of eDNA (environmental DNA) method is highly effective at accumulating information on many organisms that inhabit paddy field ecosystems. It can indirectly identify the existence of taxa that are no longer found in the target ecosystem due to behavioral characteristics, such as those exhibited by amphibians. In the metabarcoding results of this study, genes of five species of frogs were found, but it was impossible to confirm all of the frogs’ taxa, morphological pictures, and croak sounds. On the other hand, some frog taxa were only found in the metabarcoding analysis. The eDNA of the frogs found only in the metabarcoding analysis is estimated to have been introduced from nearby areas inhabited by frogs rather than the target region. Due to the powerful analytical resolution of eDNA metabarcoding, this eDNA-based paddy field search is expected to help investigate the biodiversity in agricultural ecosystems.
