 The adult has two pairs of long , narrow , <unk> , translucent wings and a long , slender abdomen . Although they somewhat resemble dragonflies or damselflies , they belong to a different infraclass of winged insects . Antlion adults are easily distinguished from damselflies by their prominent , <unk> clubbed antennae which are about as long as the head and thorax combined . Also , the pattern of wing venation differs , and compared to damselflies , the adults are very feeble fliers and are normally found fluttering about at night in search of a mate . Adult antlions are typically nocturnal , and rarely seen by day .
