Making backyard 'hives' for native bees

We would like to make some homes for native bees for our backyard with rounds of oak wood coming from a tree which we recently removed. We need specific details about construction. I would prefer to not be removing and storing and cleaning cores, as I believe the bees are probably hardwired to do that for themselves. I have seen several species of what I think are native bees working (particularly) my mint and oregano, and I would like to let them know they are at home here.Can you provide information or suggest a reliable site? I am finding much complicated and conflicting information on the internet.

Is this a paper wasp or a hornet nest and - what can we do about it? It's about 20" up, in one of our maple trees, and about 24" tall by about 15" or so wide. I have additional photos. Is this something some organization/college/university would want, or do we just need to know how to dispose of it? Would it be occupied now?

URGENT: Should I resume feeding bees the sugar water I was distributing if they are now dying?

This is a bit of a cheat, because I'm not in Colorado, but I figure this is a general enough question to apply to any location...and there is no help listed for anyone in Europe.
I am living in Germany and started to give honey bees visiting my windowsill sugar water. I did this for about 2 weeks than realized that it wasn't a healthy thing for them. I gave plain, filtered water yesterday but became concerned that they might be starting to build a hive in my sill, so removed the water entirely today. We can't have a hive at this location because they are coming into the apartment through the window.
However, today they are still searching around for the water (of course) and I am seeing dead bees on the windowsill. I am in a total panic! Should I resume giving them water/sugar water or just leave them alone? I feel terrible. I never meant to hurt them and now I don't know what to do. The weather is very hot here and I'm afraid they became overly dependent on my sugar water as a food source. Please advise me.

Thanks so much,

Bumblebee identification HELP!

Hello, I became interested in bumblebees last year when a colony nested in a bird house in my garden. Up until then I couldn't tell the difference between bumblebees and any other kind of bee, nor did I know anything about them. A colony at my home got me interested in them and I began to notice different types of bees in my garden and their behaviors. This spring I began modifying my garden into a pollinator habitat and started an account with Bumblebee Watch. As of today I've got 7 verified species and 13 waiting to be looked over. I have a book on identifying bumblebees but I'm the blind leading the blind here - I know nothing about them and am trying to learn so I can be a better contributor. I can't find any online courses or videos. The Xerces Society had a training in Bend this summer but I was unable to attend. Can you suggest anything or refer me to another resource? Thank you!

Rhododendrons and Honey Bees

We just had 20 rhododendrons planted in our yard. We have been keeping bees and harvesting their honey for 3 years and love it. Now we heard that rhodies are toxic to bees and can contaminate honey. Should we replace these plants with other native species? The bees are very important to us.

Every time anyone uses our wooden swingset, they get stung by bees. We have looked everywhere and cannot find a hive. The bees seem to be on the offensive and come after the kids, following them across the yard and on one occasion into the house. It isn't a swarm, per se, no more than 8-10 bees in any one instance. I don't want to just spray insecticide, but we can't find a hive to relocate. Suggestions?

Can they survive outside of nest/cocoon?

Sorry if some feel these are silly questions but I don't know much about larvae or the stages they go through, except that they eventually turn into an adult of the insect that laid the eggs. I have a mason bee house with a few grass carrying wasps nesting in it. There is another grass carrying wasp that has a nest in the split of a fence post located right by the bee house. I noticed it a couple of weeks ago when I was doing yard work because I saw pieces of grass sticking out of the split and I saw the adult wasp going in and out of that area. Today while I was raking up some grass clippings, I noticed a yellow looking worm/grub laying on the board below the split post. I walked over to get a closer look and saw another one laying right by it, along with some grass pieces and other material that looked like a nest. I scooped up the larvae and the material around it with a small garden shovel and upon doing that, I saw more larvae that had come out of their cocoons. I didn't know if they were suppose to be out of the cocoon this early or if it was the fall from the post that broke them open? Should I have put them back on the board where I found them laying or put them and the nesting material back inside the little cubby hole area where the nest was from the beginning? Are they suppose to be out of their cocoon this early and live like this until they're an adult wasp or are they suppose to stay inside cocoons until next year and then break out? Can they survive outside of the cocoon at this stage? Sorry for all the questions but I'm really interested in learning the answers. Thank you for doing what you do!
