Flowers on the ground of orchards can provide substantial resources for wild pollinators of orchard trees. Few studies, however, have examined the relative importance of groundcover flowers to orchard pollination by analyzing pollen on the body surface of pollinators. Oriental persimmon trees bloom within the longer blooming period of white clover, which is occasionally found as a flowering plant on the ground of persimmon orchards in Japan. The present study compared the insect species assemblage collected on persimmon flowers with that on clover. Before persimmon bloomed, Bombus ardens ardens and Apis cerana japonica were the major visitors of clover flowers. Once persimmon bloomed, the former was the most abundant bee that visited persimmon flowers over the flowering period. Apis mellifera was captured only on clover flowers. We found numerous clover pollen grains on the body surface of bumblebees captured on persimmon flowers, but far fewer persimmon pollen grains on bees that visited clover. These findings show that B. ardens ardens utilized the clover flowers under the orchards before persimmon bloomed.

大黄蜂Bombus ardens ardens（膜翅目：Apidae）在东方柿子开花前参观果园里的白三叶草
果园地面上的花朵可以为果园树的野生传粉者提供大量资源。然而，很少有研究通过分析授粉媒介体表上的花粉来研究地被植物花对果园授粉的相对重要性。东方柿树在较长的白三叶草开花期开花，在日本的柿果园地面上偶尔会发现它是开花植物。本研究比较了柿花和三叶草上收集的昆虫种类。柿子开花前，熊蜂和草蜜蜂都是三叶草花的主要游客。柿子一旦开花，前者是在开花期访问柿子花的最丰富的蜜蜂。蜜蜂仅在三叶草花上捕获。我们在柿子花上捕获的大黄蜂的体表上发现了许多三叶草花粉粒，但是拜访三叶草的蜜蜂上的柿子花粉粒却少得多。这些发现表明，在柿子开花之前，B。ardens ardens利用果园下的三叶草花。
