Haw<\/wbr>thorn flies are actually mosquitoes and belong to the family of March flies (Bibionidae)<\/em>. Haw<\/wbr>thorn flies are found all over the world and have 12 genera and over 600 species.
\nHaw<\/wbr>thorn flies are between 4 and 9 mm in size, are black and, unlike many other insects, have “thick” legs. In spring, they appear in large numbers.
\nThe female fly lays her eggs in a clump in grassland, preferably near manure. The legless larvae resemble leatherjackets<\/a> but have a black head – that of leather<\/wbr>jackets is brown.
\nThe larvae live on dead plant parts and manure residues, later on grass. The damage to the turf only becomes visible in the fall.
\nBirds<\/a> (starlings and gulls) are among the natural enemies of haw<\/wbr>thorn fly larvae.[\/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_1580555025037{padding-left: 15px !important;}”]<\/p>\n
