No natural history or ecological knowledge is known, but we hypothesize that the strikingly contrasting black and red coloration is at the same time cryptic and aposematic, and may also be mimetic. Based on observations of other species, we know that low vegetation is a common habitat of members of this genus. In a dense forest, predators from above may confuse the black dorsum of
|
|
<taxonomicName lsidName="Z. championi" pageId="0" pageNumber="8150" rank="species" species="championi">Z. championi</taxonomicName>
|
|
with dark forest background, while the strong contrast formed by black and red colors is highly visible to predators (e.g., lizards) at the same level or approaching from below. Like many assassin bugs, species of
|
|

|
|
may inflict a painful bite when attacked. Besides, harpactorines, including

|
|
spp., emit a foul odor when handled. We do not know if vertebrate predators are deterred by this odor, but it is strong enough to be detected by a human even meters away. Hence
|
|
<taxonomicName lsidName="Z. championi" pageId="0" pageNumber="8150" rank="species" species="championi">Z. championi</taxonomicName>
|
|
may be well defended against predators and the contrasting coloration serves as a signal for unpalatability. Of course, many other species of
|
|
<taxonomicName class="Insecta" family="Reduviidae" genus="Zelus" higherTaxonomySource="CoL" kingdom="Animalia" lsidName="Zelus" order="Hemiptera" pageId="0" pageNumber="8150" phylum="Arthropoda" rank="genus">Zelus</taxonomicName>

are dull colored, but expected to have the same kind of physical or chemical defense. There may be other ecological factors that determine the coloration of
|
|
<taxonomicName lsidName="Z. championi" pageId="0" pageNumber="8150" rank="species" species="championi">Z. championi</taxonomicName>
|
|
. We suspect that mimicry is one. Many other unpalatable insects show similar contrasting bright red and black color patterns.

. On the basis of pubescence, pronotal armature and whitish exudation, Champion himself questioned the conspecificity of this male with the three females of the original type series. As more material was available for the present work, his doubts have been substantiated, the male of
