Eastern parson spiders are fascinating creatures, known for their unique appearance and a distinctive white pattern on their abdomen. Studying the differences between male and female parson spiders can help us understand their biology and behavior better.
Male and female eastern parson spiders, scientifically known as Herpyllus ecclesiasticus, do exhibit some differences in size, color, and markings. Males tend to be smaller, while females often grow larger with an abdomen that exhibits a more pronounced white pattern, resembling a clerical collar worn in the past by clergy. This pattern is the primary reason for their common name “parson spider.”

Reproductive Organs
The reproductive system of parson spiders, like all spiders, is unique. The male spider uses specially adapted appendages called pedipalps to transfer sperm to the female spider during mating 2. In general, spiders have the following reproductive characteristics:
- Unique anatomy for internal fertilization
- Male’s courtship behavior adapted to increase survival chances during mating
- Female spiders may sometimes eat the male after mating
In summary, Eastern Parson Spiders have distinctive color patterns on their cephalothorax, abdomen, and legs. There is a slight difference in size between males and females. The spiders exhibit unique anatomy and behavior related to reproduction, with males using their pedipalps for internal fertilization.
Behavior and Habitat
Hunting
Eastern parson spiders (Herpyllus ecclesiasticus) are skilled hunters, primarily active at night. They do not use webs for capturing prey, and instead, they actively search for insects and other arthropods to consume. Some examples of their prey include:
- Flies
- Ants
- Beetles
Hibernation
As the temperature drops in the fall, these spiders prepare to hibernate by seeking shelter under:
- Stones
- Logs
- Bark
- Leaves
During this time, their range does not spread far from their habitat, reducing the chance of encountering predators.
Maternal Care
Female parson spiders show remarkable care for their egg sac. They carry it around and protect it from potential threats. Upon hatching, the spiderlings remain in the same habitat as their mother, gradually developing into adults.
Selected characteristics of Eastern Parson Spider
| Female | Male |
|---|---|

Venom and Bites
Severity
The Eastern Parson Spider (Herpyllus ecclesiasticus) is known for its distinctive white dorsal pattern on the abdomen, resembling a clerical collar (^1^). Although spider bites are a common concern, Parson Spider bites are typically not dangerous and cause only mild symptoms. Some possible symptoms resulting from a spider bite include itching or rash, and pain radiating from the site of the bite.
Allergic Reactions
While most people experience only mild symptoms following a Parson Spider bite, others may develop an allergic reaction, with symptoms ranging from mild to severe. In rare cases, a severe allergic reaction (anaphylaxis) can be life-threatening. Some symptoms of an allergic reaction to a spider bite may include:
- Increased sweating
- Muscle pain or cramping
- Reddish to purplish color or blister around the bite
In case of severe allergic reactions, immediate medical attention is necessary.
