We NEED to address the topic of s*xing Phidippus audax 🕷
This species is frequently misidentified, often due to confusion with Phidippus regius. The most reliable method for accurately s*xing any Phidippus species is by examining the pedipalps.
Juvenile Phidippus audax are extremely difficult - if not impossible - to s*x, as males and females appear nearly identical at this stage. Clear distinctions will emerge at the sub-adult stage. In sub-adult males, the pedipalps become noticeably bulbous, while in females they remain thin and straight.
In mature individuals, s*xual characteristics become more pronounced. Males possess a gonopore on the underside and develop distinctly comma-shaped pedipalps, with visible palpal bulbs. Their pedipalps are black with thick white coloration at the top. Females, on the other hand, retain their thin, straight pedipalps into maturity, with visible stripes.
Additionally, mature females develop a visible epigyne on the underside, which appears shiny.
It will be visible but underdeveloped when they are sub-adult, generally appearing fluffy and looking like there is a little "cover" over it.
When identifying whether a spider is male or female, it’s always helpful to start by considering the species. Is it one you’re familiar with?
For example, many keepers of Phidippus regius may come across a female audax and assume it’s male due to the green chelicerae and black-and-white colouring. It’s a very common and understandable mix-up.
This isn’t about calling anyone out - these mistakes are easy to make. The goal is simply to encourage careful identification and help reduce the spread of misinformation within the community 🩷
