 Scolytus intricatus

[Preferred Common Name]

 European oak bark beetle

[Notes on Taxonomy and Nomenclature] Ratzeburg originally described S. intricatus in 1837 as Eccoptogaster intricatus. Several synonyms have been described. According to Wood and Bright (1992) the senior available name is picicolor but intricatus is retained because of its long-standing, widely accepted use.

[\textbackslash n] [...] [Description] [::Eggs]

Scolytidae eggs are smooth, ovoid, white and translucent. They are approximately 1 mm long and individually deposited on opposite sides of the egg gallery.

[::Larvae]

All scolytidae larvae are similar in appearance and difficult to separate. They are white, 'C'-shaped and legless. The head capsule is lightly sclerotized and amber with dark, well-developed mouthparts. Each abdominal segment has two to three tergal folds and the pleuron is not longitudinally divided. The larvae do not change as they grow.

[::Pupae]

Scolytid pupae are white and mummy-like. They are exarate, with legs and wings free from the body. Some species have paired abdominal urogomphi. The elytra are either rugose or smooth, sometimes with a prominent head and thoracic tubercles.

[::Adults]

Beetles of the genus Scolytus are characterized as follows: the eyes are slightly emarginated; the antennal club is large and oval with sutures medially bowed in an acute angle; the pronotum is large; the anterior is constricted; the post and lateral margins are sharply bordered; the elytra are flat with the abdomen rising posterior from the second sternite to the apices; the tibiae are laterally smooth and possess a long curved distal tooth; and the third tarsal segments are bilobed (Grüne, 1979).

[\textbackslash n] S. intricatus has the following distinguishing characteristics: the posterior margins of the second, third and fourth sternite do not posses lateral teeth; the fourth sternite has a small medial process; the head of the males is flat, with dense setae; the overall length ranges from 2 to 3 mm; and the body colour is black with reddish-brown elytra and light-brown antennae and legs (Grüne, 1979). 

[Distribution]

S. intricatus is found throughout Europe, North Africa and the Near East (Iran and Turkey) (Wood and Bright, 1987).
