This beetle belonging to the bark beetles<\/a> family (Scolytidae)<\/em> is common on bir<\/wbr>ch trees from May through June. The Bir<\/wbr>ch Bark Beetle measures 4 to 7 mm, is dark brown and lives off the sap of the living tree.
\nThe female gnaws an up to 15 cm long tunnel just below the bark (main tunnel). On either side of the main tunnel, the female lays eggs. The larvae from the eggs gnaw long tunnels across the trunk, creating a symmetrical chewing pattern – characteristic of bark beetle chewing trails. The fully grown larvae pupate and emerge as beetles after a few weeks. The young beetles bore their way out.
\nThe bir<\/wbr>ch bark beetle, like other bark beetles, is harmful because the water supply is blocked by the tunnels under the bark, causing the tree to die.[\/vc_column_text][\/vc_column][\/vc_row][vc_row equal_height=”yes”][vc_column width=”1\/3″][vc_custom_heading text=”Where to find” font_container=”tag:h4|text_align:center|color:%23ffffff” google_fonts=”font_family:Lato%3A100%2C100italic%2C300%2C300italic%2Cregular%2Citalic%2C700%2C700italic%2C900%2C900italic|font_style:400%20regular%3A400%3Anormal” css=”.vc_custom_1537946500082{background-color: #536895 !important;}”][vc_column_text el_id=”entrytxt” el_class=”entrytxt” css=”.vc_custom_1612454485459{padding-left: 15px !important;}”]<\/p>\n
