I think we often in our minds underestimate the true number of bees in an area. Here we are in average suburbia with lots of development and have this many bumble bees at one place. When sampling bees we never reach anywhere this number under any circumstance I have seen. Thus we have to wonder how representative some of our low number samples might be, with the notion that we need to probably err on higher capture rates in our studies rather than lower.</div><div><br></div><div>sam</div><div><br></div><div><div>The earth has many keys,</div><div>Where melody is not<br></div><div>Is the unknown peninsula.<br></div><div>Beauty is nature's fact.<br></div><div><br></div><div>But witness for her land,<br></div><div>And witness for her sea,<br></div><div>The cricket is her utmost<br></div><div>Of elegy to me. <br></div><div><br></div><div> - Emily Dickinson</div></div><span class="HOEnZb"><font color="#888888"><div><br></div><div><br></div><div><br></div><div><br></div><br clear="all"><div><br></div>-- <br><div class="m_7880445383887972538gmail_signature"><div dir="ltr"><div><div dir="ltr"><div style="text-align:center"><i><b>Why Did you Mow My Flowers? </b></i></div><div style="text-align:center"><i><b>- Bee</b></i></div><div style="text-align:center"><br></div></div></div></div></div>
