Input: [header] How to identify wasps [title] Look for yellow and black. [step] Identify yellowjackets and european paper wasps by the yellow and black bands on the wasps' abdomens. Cicada killers are a type of digger wasp that resembles a larger, wider yellowjacket. <sep> (A) Identify the european hornet by its yellow and black striped tail and red-brown thorax. You'll also see black and yellow mud daubers. (B) They are very active wasps, so due to their relaxed sexation, wasps can only communicate to larger wasps and prey on small amounts of smaller wasps. [substeps] Cobra wasps, on the other hand, are horizontal wasps that resemble short, oddly shaped wasps. (C) Place a magnifying glass on the wasps' abdomens and pay attention to them as they fly overhead. [substeps] Wasps will often fly in pairs, especially if they are just looking for food. (D) [substeps] Wasps can be as large or as small as you'd like to have wasps. Brown wasps can be larger, but they may be less realistic.
