Description

edit

Adult H. tredecimpunctata have domed backs, mainly oval, often shiny with short legs and antennae. They have two wing covers. They are usually red to orange in color. This species has thirteen dark or black spots.[1] The larvae are slightly flattened and covered with miniature spines. Very small eggs are laid in groups of 10–50 on the undersides of leaves.

Range

edit

The species is distributed throughout much the northern hemisphere-Europe, North Africa, European Russia, the Caucasus, Siberia, the Russian Far East, Belarus, Ukraine, Moldova, Transcaucasia, Kazakhstan, Middle Asia, Western Asia, Afghanistan, Mongolia, China, the Korean Peninsula, Japan, North America.[2][3] In North America, it can be found in Canada and the northern United States. The relative abundance of this species has decreased in many regions (midwestern US, Maine, Quebec, and New Brunswick) following the introduction of the non-native ladybeetle Coccinella septempunctata. On the other hand, H. tredecimpunctata appears to coexist with non-native ladybeetles in Manitoba and Ontario.[1]

Habitat

edit

It is a stenotypic (limited habitat) species most associated with wet meadows, lakesides, flood plains and river deltas, marshes, and in marshes and marshy alder thickets, carr and bodden on Carex, Sparganium, Phragmites, and on Salix[4][5]

Biology

edit

It feeds on Aphis farinosa and occurs on grasses and sedges associated with Sipha glyceriae and on aphids associated with Gramineae, Umbelliferae, and some other plants.[6] It also feeds on Erysiphales on reeds, before the emergence of aphids.[7] It has also found on cane, rotten hay, detritus, and under peeled-off bark.
