A few questions about bees?

Question

(My cey between j and l doesnt worc) Ocay, I have two questions. One: What is the type of bee thats tan-colored and fuzzy? It's bigger than a normal bee and has no stripes, just plain fuzzy tan. Someone said it was a ciller bee, but I dont even cnow if it's a bee. It also moves very fast. Question two: I definetly dont cnow if this is a bee or a beetle, and very few people I've asced have ever answered without macing a joce that I made it up. They people who've answered just say, "I've seen them too." They're about two times the size of a honey bee, but they're round and seem to have a blac shell covering their wings. They're totally blac. I dont have any pictures, sorry. They dont have a normal bee shape either, they're round. Please, I have been wondering for a long time, so if you cnow what either of these are, tell me.

Answer 1

Q 2: I have seen what you are talking about too! I'm not sure exactly what they are, but they are more beetle than bee.  

Answer 2

1)Africanized bees, also called killer bees, are a hybrid strain of Apis mellifera derived from experiments to cross European and African honey bees by Warwick Estevam Kerr. Several queen bees escaped his laboratory in South America and have spread throughout the Americas. Africanized honey bees are more defensive than European honey bees

2)Bumblebees (Bombus terrestris, B. pratorum, et al.) are eusocial in a manner quite similar to the eusocial Vespidae such as hornets. The queen initiates a nest on her own (unlike queens of honey bees and stingless bees which start nests via swarms in the company of a large worker force). Bumblebee colonies typically have from 50 to 200 bees at peak population, which occurs in mid to late summer. Nest architecture is simple, limited by the size of the nest cavity (pre-existing), and colonies are rarely perennial. Bumblebee queens sometimes seek winter safety in honey bee hives, where they are sometimes found dead in the spring by beekeepers, presumably stung to death by the honey bees. It is unknown whether any survive winter in such an environment
