使用冷蒽酮测试，在现场收集的蜘蛛进行取样，以确定植物糖（果糖）的存在。这些蜘蛛来自三个不同的栖息地：一片棉花地，一片油菜和蚕豆混合的田地，以及一个有开花的木本和草本植物的公园。比较了不同生境、不同性别、不同年龄三突艾伯菌（Ebrechtella tricuspidata（F.）（蜘蛛目蜘蛛科）。在745只野外采集的蜘蛛中，18.7%的蜘蛛对果糖呈阳性反应，表明这些蜘蛛以植物花蜜为食。在所代表的12个蜘蛛科中，来自9个科的个体对果糖呈阳性：Oxyopidae、Escherisidae、Pisauridae、Salticidae、Lycosidae、Tetragnathidae、Araneidae、Nephilidae和Agelenidae。其他三个家庭（Linyphiidae，Clubionidae和Theridididae）的所有成员均为果糖阴性。3种生境中蜘蛛取食花蜜的比例无显著差异：棉田为19.3%，油菜蚕豆混播区为16.6%，木本和草本植物公园为20.0%。大肠在三尖齿动物中，雌性动物的阳性率明显高于雄性动物（87.5%对42.9%）;未成熟动物的阳性率低于成年动物（分别为26.5%和66.7%）。
Using cold-anthrone tests, spiders collected in the field were sampled for the presence of plant sugar (fructose). The spiders came from three different habitats: a cotton field, a mixed rape and fava bean field, and a park with flowering woody and herbaceous plants. The percentages of fructose-positive spiders were compared among the different habitats, as well as among the different sexes and ages of Ebrechtella tricuspidata (F.) (Araneae Thomisidae). Out of 745 field-collected spiders, 18.7% were positive for fructose, indicating that these spiders feed on plant nectar. Of the 12 families of spiders represented, individuals from 9 families were positive for fructose: Oxyopidae, Thomisidae, Pisauridae, Salticidae, Lycosidae, Tetragnathidae, Araneidae, Nephilidae, and Agelenidae. All members of the other three families (Linyphiidae, Clubionidae and Theridiidae) were negative for fructose. There were no differences for nectar feeding in spiders among the three habitats: 19.3% of individuals from the cotton field, 16.6% from the mixed rape and fava bean field, and 20.0% in park with flowering woody and herbaceous plants tested positive for fructose. For E. tricuspidata, significantly more females were positive than males (87.5% versus 42.9%); and immatures tested positive at a lower rate than adults (26.5% and 66.7%, respectively).
