Explanation of Names
Tetragnatha laboriosa Hentz, 1850
Female: Length 5.2-9.0 mm(1)
Male: Length 3.8-7.4 mm(1)
Not diagnostic, but can separate some species:(1)
Lateral eyes as far apart as medians.
All across the US and Canada
Often found in fields, but lives in many habitats.
Laboriosa has silvery patches on abdomen and the lateral eyes are distinctly separated from each other. The carapace marks are straight, diverging lines. Actually, the carapace pattern (which Levi doesn't mention) is just about the most reliable of all.
