Roan antelope
Roan antelope are found in woodland and grassland savanna, mainly in the tropical and subtropical grasslands, savannas, and shrublands biome, which range in tree density from forest with a grassy understorey (such as central Zambezian Miombo woodlands) to grasslands dotted with few trees, where they eat midlength grasses. They form harem groups of five to 15 animals with a dominant male. Roan antelope commonly fight among themselves for dominance of their herd, brandishing their horns while both animals are on their knees.
Spider wasp
Adult Pompilidae are nectar-feeding insects and feed on a variety of plants, mostly leaves of the eucalyptus tree. The female wasps search for a variety of spiders for their larva to feed on, including wolf spiders ("Lycosidae"), huntsman spiders ("Sparassidae"), and baboon spiders ("Harpactirinae"). As the larva feeds on its host, it saves the vital organs, such as the heart and central nervous system, for last. By waiting until the final larval instar, it ensures the spider will not decompose before the larva has fully developed.
