The plastic jar with the lady bugs is okay. There are no spots on the lady bugs, which I found odd, since in the book the part about lady bugs specifies the number of spots on their backs.
I remembered reading this, and took a look at the bug jars with the nature sets they had on display at the Dallas Bistro today (I didn't buy it, so I probably shouldn't do a full review). All of the bug jars I saw there had ladybugs with spots, so maybe yours was just a mistake?
I dunno, but I thought I should mention it just in case someone was turned off the set by the thought of spotless ladybugs.
