Abstract: A sectional shelter is made of a set of panels of plastic material arranged side by side, along with a plastic roof cap. The panels are coupled by ribs projecting from one edge portion of each panel and a channel along the other edge portion. Retainers are pivotally mounted on the inside of the wall adjacent the channeled edge portion so that the edge portion carrying the ribs may be captured between the inside wall of the panel and the retainer. The shelter has curved and straight panels so that it may have various configurations. Door and window openings are formed in the wall panels and are closed by doors and windows fastened on the panels.

Abstract: A hole in a leafcutter bee nest is stripped by pushing a thin tube into the hole to separate larvae in the hole from the surrounding nest material. An ejector, for example a rod sliding in the tube, is used to eject the separated larvae and cocoons. The method is carried out using an apparatus with foot guides for engaging a nesting block and aligning the tubes with a row of holes in the block, and a sequential drive. The drive first pushes the tubes through the block then drives the rods through the tubes. The tubes and rods are then withdrawn. The foot guide is subsequently lifted out of engagement with the nesting block and the block is indexed one hole forwards for stripping of the next row of holes.

Abstract: A portable shelter especially for leafcutter bee nest, consists of six identical molded plastic panels and a molded roof cap. The panels are fastened together using molded in place tabs and pins to form a circular wall that is domed at the top and capped at the center with the roof cap, also fastened in place with integral pins and holes in a peripheral flange.
