This five-mm-long sawfly is native to East Asia and was first spotted in Europe (Hungary and Poland) just before World War II. Meanwhile, the elm zigzag sawfly is common in Europe. In general, the sawflies cause little damage to elms (the host plant<\/a>). As these sawflies become more common, the likelihood of damage to elms increases, as in some areas of England. Severe infestation weakens the elm, making it more susceptible to Dutch elm disease<\/a>.
\nThe females of Elm zigzag sawfly are active from April to mid-September. During that period, females produce an average of five generations. The larvae (caterpillars) hibernate as cocoons in the ground.
\nThe caterpillar like larvae of the elm zig zag sawfly live off the leaves of the elm and make the characteristic zigzag pattern.
\nThe parasitic fly (Blondelia nigripes)<\/em> is among the natural enemies of the elm zigzag sawfly.[\/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_1677777424837{padding-left: 15px !important;}”]<\/p>\n
