<p class="ecxMsoNormal" style="margin: 0in 0in 10pt; line-height: 13pt;">We found that
territorial males of Anthidium manicatum would attack most any flower-visitor to
Stachys byzanthina, especially honeybees. Some attacks resulted in the death of
the intruder, mostly honeybees and occasionally a bumblebee. Long-tongued
solitary bees such as Megachile and Anthophora were generally too nimble. </p>
<p class="ecxMsoNormal" style="margin: 0in 0in 10pt; line-height: 13pt;">They did not
kill by puncture; rather the base of one of the forewings gets torn or broken,
making the victim unable to fly.</p>
<p class="ecxMsoNormal" style="margin: 0in 0in 10pt; line-height: 13pt;">The species
only shows territorial behavior if the flowers it defends are numerous and
clumped together.</p>

territorial males occur at least in Anthidium and Megachile (e.g., the aptly
name M. pugnata), though only Anthidium (some but not all species) have actual
"prongs" that could be used to puncture. It is perhaps not a coincidence that
Anthidium is one of the few bee genera where males are substantially larger than
females. The ability of manicatum to wound other bees has been noted in the
literature and anecdotally for many years; I'm not aware of any other species
known to do this.<br><br>Peace,<br><pre>--
