Abstract

Butterflies are flower visitors and are important for plant pollinators. This research aimed to analyze the food plant preferences of butterflies and analyze the correlation between butterfly proboscis and flower corolla tube lengths.  Observations of butterflies were carried out at four locations within Dramaga campus area of Bogor Agricultural University from March to April 2024. The results showed 23 species of butterflies were observed on the flowers of eighteen plant species. Hesperiids and Nymphalids butterflies were found dominantly. The shrub plant, Lantana camara is the most visited by butterflies (8 species), followed by Saraca indica (6 species), and Turnera ulmifolia (5 species). Butterflies prefer to visit tubular shape and purple color of flowers. Based on the correlation analysis, there was no significant correlation between the butterfly proboscis and the flower corolla tube lengths.

Abstract

Macrobrachium pilimanus is a type of freshwater prawn commonly found in Indonesian waters. This species is reported to have abbreviated larval development (ALD), and its life cycle is greatly influenced by the conditions of their environment, including the water currents. This study examined the relationship between water currents and the daily behavior of the M. pilimanus freshwater prawn. We observed the behavioral pattern using the scan sampling method on six individuals from two treatments (strong current and slow current) over 64 hours, with observations taken every 60 minutes. Our results showed a dominant behavior of M. pilimanus hiding in places with strong currents and high ingestion behavior. In contrast, the prawns that were not exposed to water currents predominantly showed partially inactive behavior.
