Distribution
[edit]Adalia decempunctata is a common Palearctic species found in Europe, North Africa, European Russia, the Caucasus, Siberia, Belarus, Ukraine, Moldova, Transcaucasia and western Asia.[1][5][6]
Description
[edit]Adalia decempunctata can reach a body length of about 3.5–5 mm (0.14–0.20 in). This species is highly variable. Individuals may in fact have a red, orange or brown ground colour and between 0 and 12 distinct dark elytral spots, although rarely more spots have been recorded, up to 15 spots. These beetles have a glabrous body, with an almost round form. Legs and antennae are usually brown or orange.[7] The species includes eight varietas, with three basic forms. The light form shows five to seven black spots on the pronotum and several black spots on the red-orange elytra. The dark form is mainly black or brown in color, and the pronotum has a light border on the sides and front. The mixed form has black or brown in color elytra, each with five orange to red spots. Sometimes these ladybirds have no spots at all.
Biology
[edit]It occurs in western European broadleaf forests eastern deciduous forests, Sarmatic mixed forests, at forest edges, and in parks and gardens wastelands and in Eurasian Steppe, Pannonian Steppe biotopes. It is found on bushes and deciduous trees, on grasses, under bark, in moss on trees, in leaf litter, on brushwood, coarse woody debris and in alluvial soil.[8]
The insects feed on aphids on trees and bushes.[9] The adults overwinter in litter and among fallen leaves.
