Brenhines Gacynen y Llus \u00a9 Susan Loose<\/p><\/div>\n

Ydych chi wedi gweld y Wenynen hon?<\/h2>\n

Mae’r Gacynen y Llus (Bombus monticola) yn un o’n cacwn mwyaf prydferth! Fel awgrymir gan yr enw, gellir dod o hyd iddo yn bennaf o fewn ardaloedd lle mae Llus yn tyfu ar ucheldiroedd a rhostiroedd y DU, gan gynnwys Cymru. Am fwy o wybodaeth gweler y tudalen Rhywogaeth BBCT<\/a><\/span><\/strong>.<\/p>\n

Pam ydym ni’n chwilio amdano?<\/h2>\n

Mae tystiolaeth yn awgrymu bod Cacwn y Llus yn prinhau yn y DU, mwy na thebyg o ganlyniad i golled cynefinoedd. Yng Nghymru, mae cofnodion yn dangos gostyngiad yn amrediad Cacwn y Llus, sy\u2019n dangos dirywiad tebyg i weddill y DU.<\/p>\n

Rydyn ni angen mwy o gofnodion o ble mae Cacwn y Llus, a dyna le rydych chi’n dod i mewn! Mae pob cofnod a welwyd yn cyfrannu at ein dealltwriaeth a chadwraeth o’r rhywogaeth yn y dyfodol.<\/p>\n

Sut gallwch chi helpu?<\/h2>\n

Rydyn ni\u2019n gofyn i bobl trosglwyddo eu gweliadau o Gacwn y Llus, tra allan yng Nghymru yn 2022.<\/p>\n

Adnabod y Gacynen y Llus<\/em><\/h3>\n

Dod o hyd i Gacwn y Llus<\/em><\/h3>\n

Fel mae’r enw’n awgrymu, mae’r rhywogaeth hon yn gysylltiedig ag ardaloedd lle mae clystyrau da o Lus<\/strong><\/a>,<\/span><\/span> sy’n blodeuo o tua diwedd Ebrill i ddechrau Mehefin. Mae’r breninesau’n dueddol o ddod i’r amlwg pan fydd y llus yn ei flodeuo, gyda gweithwyr yn ymddangos tua mis Mai a mis Mehefin, a’r gwrywod ychydig yn ddiweddarach tua Gorffennaf ac Awst. Gellir dod o hyd i\u2019r breninesau yn arbennig yn bwydo ar lus er y bydd y gweithwyr a\u2019r gwrywod yn cael eu denu at flodau eraill gan gynnwys meillion, mwyar, grug a throed y i\u00e2r.<\/p>\n

I\u2019ch helpu gyda\u2019ch chwiliad rydym wedi creu dau fap rhyngweithiol \u2013 un ar gyfer Llus ac un ar gyfer Cacwn y Llus.<\/p>\n

Yn y b\u00f4n, mae’n werth edrych ar ardaloedd ucheldir gyda Llus a blodau eraill ynghyd \u00e2 rhostiroedd arfordirol!<\/p>\n
