切叶蜂的特点是在腹部生有一簇金**的短毛，其生活特征是筑巢时，切叶蜂到其喜爱的植物(多为蔷薇科植物)上，用宽大的上颚在叶片上切下直径约为20 mm的圆形叶片，带回巢穴后卷成筒状，并将其一端封闭，形成巢室。
切叶蜂寡食性或多食性，独栖性生活，1年繁殖1～2代。切叶蜂分雄蜂和雌蜂2种，春季雄性切叶蜂先于雌蜂出房，出房后在未出房的雌蜂巢穴上方盘旋飞行，寻找雌蜂交配，雄蜂交配后在几日内死亡。
切叶蜂其他情况简介。
切叶蜂为独栖性昆虫。在自然状态下，交配后的雌性切叶蜂，大都利用比其身体稍大，直径约7 mm的天然的孔洞，如树干上的洞穴、建筑物的洞或裂缝，以及壁蜂、木蜂和其它切叶蜂出巢后留出的空巢、甲虫等其它昆虫的蛀洞等现成的洞穴筑巢，有的利用材质较软，具木髓的植物（如玫瑰）枝干，将木髓挖除作巢，偶尔有的在地穴中筑巢。
Bees are flying insects closely related to wasps and ants. Bees are a monophyletic lineage within the superfamily Apoidea, presently classified by the unranked taxon name Anthophila. There are nearly 20,000 known species of bees in nine recognized families,[1] though many are undescribed and the actual number is probably higher. They are found on every continent except Antarctica, in every habitat on the planet that contains insect-pollinated flowering plants. Bees are adapted for feeding on nectar and pollen, the former primarily as an energy source and the latter primarily for protein and other nutrients. Most pollen is used as food for larvae. Bees have a long proboscis (a complex "tongue") that enables them to obtain the nectar from flowers. They have antennae almost universally made up of 13 segments in males and 12 in females, as is typical for the superfamily. Bees all have two pairs of wings, the hind pair being the smaller of the two; in a very few species, one sex or caste has relatively short wings that make flight difficult or impossible, but none is wingless. The smallest bee is Trigona minima, a stingless bee whose workers are about 2.1 mm (5/64") long. The largest bee in the world is Megachile pluto, a leafcutter bee whose females can attain a length of 39 mm (1.5"). Members of the family Halictidae, or sweat bees, are the most common type of bee in the Northern Hemisphere, though they are small and often mistaken for wasps or flies. The best-known bee species is the European honey bee, which, as its name suggests, produces honey, as do a few other types of bee. Human management of this species is known as beekeeping or apiculture. Bees are the favorite meal of Merops apiaster, the bee-eater bird. Other common predators are kingbirds, mockingbirds, bee wolves and dragonflies.
