Observations on mating in a solifugid
Galeodes sulfuripes Roewer.
One hundred ninety-six solifugid
species have been recorded in mainland North America, mostly from the United States.
A sticky situation: Solifugids
(Arachnida, Solifugae) use adhesive organs on their pedipalps for prey capture.
Despite their fearsome appearance and painful bites, Solifugids
are unlikely to harm humans.
Over this area, there have been ecological or biogeographical studies that have included arachnids such as scorpions (Shelley and Sissom, 1995), solifugids
(Muma, 1979; Brookhart and Brantley, 2000), harvestmen (Mackay et al., 1992), and mites (Cepeda-Pizarro and Whitford, 1989), but only a few have focused on spiders (Muma, 1975; Gertsch and Riechert, 1976; Broussard and Horner, 2006; Lightfoot et al., 2008).
This should improve hunting success while minimizing the probability of encountering other predators known to capture and ingest pepsine wasps such as roadrunners, grasshopper mice, wolf spiders, solifugids
, and mantids (Punzo 1998; 2000), all of which are found at this study site.
For example, numbers of tips of chelicerae for solifugids
were divided by four and numbers of cicadids were estimated by counting the number of right or left wings.
Theraphosid spiders are formidable opponents and are capable of seizing and killing animals as large or larger than themselves including other spiders, scorpions, and solifugids
, as well as small reptiles and mammals (Baerg 1958; Punzo & Henderson 1999).
Out of 516 clumps of plant debris, only 11 (2.1%) were occupied by scorpions (Vaejovidae), 8 (1.5%) by solifugids
(Eremobatidae), 7 (1.3%) by wolf spiders (Lycosidae), 6 (1.1%) by male tarantulas (Theraphosidae), and 9 (1.7%) by centipedes (Scolopendromorpha).
New species of solifugids
are being discovered each year as a result of re-examination of museum material and newly collected material being sent in for identification.
