Invertebrate

Biological and ecological surveys confirmed the presence of 14 butterfly species. Hymenoptera Aculeata are represented with five species, of which shrill carder-bee, buff-tailed bumblebee and the red-tailed bumblebee are strictly protected as they are endangered. Molluscs are represented with two common varieties: the garden stain and Xerolenta obvia land snail. Shrill carder-bee (Bombus sylvarum) is a representative of Hymenoptera Aculeata, family Apidae. The queen grows to 16 – 18 mm and makes a “shrill” sound when flying. It is less conspicuously coloured in a palette of greys and beiges, with a dark “target” on the chest. The third abdominal segment, which is grey, bears a pronounced dark stripe. The other abdominal segments are intermittently grey and reddish striped. Both sexes are the same colour. In contrary to its name, the shrill carder-bee inhabits open areas. A nest with a mean number of bees is built shallowly underground. Peculiar wax pockets are built to house the larvae. The worker bees store pollen and honey in them. Larvae are not fed by worker bees but consume the food which is stored underneath them.

Red-tailed bumblebee (Bombus lapidarius) The queen is 20 – 23 mm long, with a black body and a flaming-red tip of her abdomen. Worker bees are similarly coloured. The male has a domed forehead and protorax. In nature, the bees are most commonly seen when dead-nettle is in bloom. The bumblebee most commonly forms large colonies with several hundred bees living underground. Like bees, the workers store pollen and honey in special way pockets and feed the larvae from the accumulated stock.
