Identification
Family: Buthidae

Scientific Names: Buthus occitanus occitanus
Common Names:
Description
Medium to large scorpion, adults up to 7.5+ cm long. Body, pedipalps & post-abdomen all dark-brown, legs lighter, brown to yellowish-brown; post-abdomen relatively thick & wide (but not as much as for Androctonus spp.).


Habitat
Found mainly in semi-arid, arid, or desert areas w/ limited vegetation, sometimes in margins of cultivated land & oases; from near sea level up to at least 300 m elevation. Widely distributed in southern Europe, on several Mediterranean islands, northern Africa & the Middle East.
Activity and Behavior
Nocturnal, preys mainly on insects & other arthropods, sometimes eats small lizards, too. Mating includes elaborate courtship "dance." Young hatch within female & later crawl out her genital opening. Young sometimes climb onto female's dorsum, & may crawl down & feed on body juices of prey she is concurrently consuming.
Venom Characteristics
Mainly neurotoxic, w/ possible cardiotoxic & cytotoxic factors. Usually causes intense local pain, slight local swelling, w/ systemic circulatory problems & shock being the reported cause of death. More than 25% of seriously envenomated people were <10 years old (5 of 28 died in one North African report). The only medically important scorpion found in southern Europe, but venom seems more potent in N. African subspecies.

Latrodectus mactans
Identification
Family: Theridiidae
Scientific Names: Aranea mactans, Latrodectus albomaculatus, L. formidabilis, L. insularis insularis, L. i. lunulifer, L. intersector, L. mactans mexicanus, L. m. texanus, L. perfidus, L. sagittifer, Tetragnatha zorilla, Theridion lineatum, T. lineamentum, T. verecundum [Note: This is one of the 2 most geographically wide-spread & best known of at least 31 currently valid species in this genus.]
Common Names: Black Widow Spider, Southern Black Widow, red-back spider, jockey spider, Katipo, viuda negra, chiranthahua, arana brava, casampulga, la coya, arana naranja
Description
Medium-sized cobweb spider, females' body (cephalothorax + abdomen) usually 10-15 mm long, satiny dark-brown to black w/ reddish "hourglass" mark on posterior ventral abdomen, often w/ a reddish spot on dorsal abdomen just above its tip. Female abdomen rounded & globular. Males much smaller, rather slender w/ relatively long legs. Males & young often w/ varying pattern of many stripes or blotches of red, white & brown on body.



Habitat
Most often found hanging in typical "cobwebs" in upper corners of basements, crawl spaces, outbuildings, & under seats of outdoor privies, usually near garbage or debris, wherever insect prey is abundant. Geographically wide spread. Found in southern U.S. (New York to northern California & southward), several Caribbean islands, Mexico, & Central & parts of South America.
Activity and Behavior
Mainly nocturnal, hangs in web awaiting prey, usually tries to get away from large animals & people, but will often aggressively defend its egg clusters (sacs) which it has hung in its web. Feeds on nearly any kind of insect or arthropod which gets caught in its web. Males are not always eaten after mating w/ a female, usually only if female has not fed recently, but he is often "biologically spent" & dies soon afterward anyway.
Venom Characteristics
Mainly neurotoxic (presynaptic sites). Bite usually like a pinprick, often not felt 'til 15 min. later, then pain may be locally intense. Severe envenomation causes symptoms like spreading intense pain, lots of sweating, fast & shallow breathing, eyelids swollen, alternating excess & lack of salivation, cardiac rate & rhythm changes, rigid abdominal muscles, sight impaired (seeing "light" spots). Human fatalities rare (<5%, untreated) & often due to additional medical problems.

Latrodectus tredecimguttatus

Common Names: Mediterranean widow spider, European widow spider, North African Widow spider, 13-spotted widow spider, ragno rosso, malmignatte, la malmignatte, roga, marmaga, bou siha, tendarman, saeuss, crna baba, crve-ni pauk, karakurt, chim
Description
Medium-sized cobweb spider, female's body (cephalothorax + abdomen) usually 9-18 mm long (male's body usually 4-7 mm long & much thinner). Female abdomen globular, very dark-brown to black, usually w/ many (typically 13, up to 17; rarely no markings) moderately large dorsal red blotches in an irregular pattern. Young w/ paler body, red, orange, & white stripes &/or spots in various patterns.



Habitat
Mainly found outdoors, hanging in its typical cobweb in partly sheltered, partly shaded, moderately humid situations (like under an awning, crawl space, wood pile, eave, or window frame) w/ adequate populations of prey insects (or arthropods) nearby. This species is very wide spread around the Mediterranean Sea in southern Europe, northern Africa & the Middle East, also found in Russia.
Activity and Behavior
Mainly nocturnal. Usually avoids large animals & humans, but females sometimes will aggressively defend their egg sacs hanging in their web. Prey mainly on available insects or arthropods which get caught in its web. Males may be eaten by females after mating, but not always (unless female has not fed recently). Usually bite humans only if molested, stepped on, or pinched in clothing being donned.
Venom Characteristics
Neurotoxic (at pre-synaptic sites). Envenomation (bite) not usually felt for several minutes. May cause intense local pain, followed by spreading pain, sweating, lacrymation, muscle spasms, heart or breathing difficulties, impaired vision, rigid (& painful) abdominal muscle wall, sometimes nausea & vomiting. Envenomation by this species currently causes a few human fatalities annually, mainly of children (about 5% of untreated severe envenomations).

Loxosceles rufescens
Identification
Family: Loxoscelidae
Scientific Names: Scytodes rufescens, Loxosceles marylandica
Common Names: The Mediterranean Recluse, Brown spider, violin spider
Description
Female w/ body usually 7-12 mm long (up to 15 mm). Usually medium-brown to dark chestnut-brown, w/ slightly darker brown "violin shaped" mark on top of carapace (its base along the front margin). Only 6 eyes (in 3 pairs, or diads) around the front edge of the "violin's" base. Abdomen often lighter, legs fairly long, slender & w/ no marks, stripes or obvious strong spines. Usually looks very much like L. reclusa but carapace darker & usually reddish-brown.



Habitat
Found mainly in fairly dry, warm, cryptic, dark, undisturbed sites, often in crevices/ narrow spaces under or beside logs, stones, boxes, or wall voids. Frequently found in sub-basements of older, heated large buildings in temperate zones. Reportedly originated in Mediterranean Europe & N. Africa, but now wide spread in tropical, sub-tropical & many temperate areas (may be nearly cosmopolitan in buildings). Sometimes found outdoors under loose bark near ground level in warm regions.
Activity and Behavior
Mainly nocturnal, "wandering hunter," typically preying on locally available insects & arthropods. Builds only a loose web in or near harborage (usually in crevices beside or under logs, stones, boxes, etc.), or to cover a clutch of eggs. Usually one of the most reclusive species in this genus & seldom encountered by humans.
Venom Characteristics
Contains moderately potent cytotoxic, hemotoxic, & neurotoxic factors. Very few human envenomations, & no well-documented human fatalities, reported as having been caused by envenomation by this species. But often misidentified as L. reclusa, or other Loxosceles spp.
