Habitat |
Description |
|
1 |
A sidewalk
outside of a small restaurant. No food for ants outside. Well-maintained
and regularly cleaned.
Used to show
the minimum degree of opportunity and maximum degree of human interference.
|
|
2 |
A rural
bus-stop located underneath a tree. Excess of food and wrappers left on the
ground. Not very well cared for and never cleaned.
Used to show
the maximum degree of opportunity and minimum degree of human interference. |
|
3 |
A river-bed
with a healthy population of green foliage. No external human sources of
food available for ants. Never maintained or cleaned. No human impact.
Used to show
the minimum degree of opportunity and minimum degree of human interference. |
|
4 |
Underneath a
shelf in a rural store. Constant supply of food from open packages on
shelves. Regularly maintained and cleaned; very well-kept.
Used to show
the maximum degree of opportunity and maximum degree of human interference. |

Table 3: Detailed Descriptions of Morphotypes
|
Morphotype |
Observation |
|
A |
Approximately 1.5-2.0 mm long.
Slender body shape with a dark black hue. Thin thorax with a
semi-translucent color Long spindly antenna. |
|
B |
Approximately 1.0-1.5 mm long.
Extremely small stubby body of a black hue. Head, thorax, and abdomen are
approximately of equal proportion. |
|
C |
Approximately 2.5-3.0 mm long.
Very large bodies, with an extremely enlarged blocky head and pincers. Red
head contrasts with black body. Apparently relatives of morphotype A. |
|
D |
Approximately 1.0-1.5 mm long.
Extremely small stubby body of a red hue. Head, thorax, and abdomen are
approximately of equal proportion. Small white spot on underside of
abdomen. |
|
E |
Approximately 2.5-3.0 mm long.
Large body with long legs. Greenish hue. Presence of 8 legs, fused thorax
and head, and distinctive body structure suggests that it is an arachnid. |
