Catafalque of Krzysztof OpaliÅski, 17th century. A catafalque is a raised bier, box, or similar platform, often movable, that is used to support the casket, coffin, or body of the deceased during a funeral or memorial service.
The catalpa tree (Catalpa bignoniodes) is native to the southern U.S. and is a nice ornamental with large, heart shaped leaves. The catalpa worm shows up in mid-summer and can only be found on the catalpa tree. It is the larva of the sphinx moth and as it eats the catalpa leaves it can grow to 5-6 inches. Normally, the tree can be completely defoliated without causing harm and new leaves regrow.
