ABSTRACT Urban area is dominated by land that  functioned  of  the  interest of  economy and  settlement,  but only a few land allocated for wildlife. The butterflies was one of the wildlife that could be found         in urban areas.The remaining habitat that can be used by butterflies assumed confined to the urban green space. Based on its life cycle, the butterflies having an initial phase (egg to larvae) is a phase which is generally require specific habitat. This research aims to determine the relationship between landscape characteristic and oviposition site preferences of butterfly. This research was conducted on April to June, 2014 at fifteen urban green spaces in East Jakarta by using descriptive survey technique. Landscape characteristics measured include area, perimeter, lawn area, closed vegetation area, open vegetation area, non vegetation area. Landscape characteristic not only measured from urban green space, but also measured from the area around urban green space within the scope of 100 meters  buffer. Results show that there is a relationship between landscape characteristic and oviposition site preferences. Significant positive correlation between the abundance and area correlation coefficients   rs (0,546), open vegetation area rs (0,758) and non vegetation buffer area rs (0,688). There was no significant correlation between the abundance with perimeter area,  lawn  area,  closed  vegetation  area,  non vegetation  area,  lawn  buffer,  open  vegetation  buffer  and  closed  vegetation  buffer.   Keywords: caterpillar,landscape characteristic, oviposition site, preferences, urban green space

Oviposition site preferences forGalerucella calmariensisandG. pusilla, biological weed control agents against purple loosestrife, were examined in 1994 and 1995. The leaves, stems, axils, and flower buds (G. pusilladid not oviposit on flower buds) were found to be the preferred oviposition sites. Oviposited egg masses may be used as a parameter within a biological control monitoring plan, providing information onGalerucellaestablishment and/or presence, estimating future population size, and providing biological control agent dispersal information. Monitoring for egg masses should concentrate on host plant leaves, where over 56% of all egg masses were oviposited.

Ventilatory patterns were examined in the Eastern lubber grasshopper Romalea guttata and correlated with respiratory transpiration. Discontinuous release of CO2 was only observed in quiescent individuals during their scotophase. Interburst periods (spiracles closed) alternated with bouts of CO2 emission and O2 consumption (burst phase); no true ‘flutter’ phase was observed. Cycle duration decreased with increasing temperature in both hydrated and dehydrated individuals. Metabolic rates for this large, sluggish species are lower than those reported for smaller and/or more active grasshoppers. Water loss rates fell within an expected range of values for arthropods from mesic environments. Respiratory transpiration accounted for only 1.9-3.9 % of the total water loss between 15 and 30 sC and for only 7 % of the water loss during the burst phase of the cycle. These data indicate that the cyclic release of CO2 in this adult insect does not result in substantial savings of water.
