And I found this one in my area: linky
TheJackal

DavidRS

I wouldn't mind adding them to my J.C. collection.
cacoseraph

i found these at East East Fork Road in Azusa and also at the Burned Lands

very attractive species


a word of caution, however... some Jcrik species are protected somehow. i might try and sort that out today if i think of it
WBurke17

I do recall that now that you mention it.
I'll find the link
cacoseraph

i think it is species that are protected and not genera so we might have to get good (er, good enough) at id'ing the various species to know what we can lift and what we need to leave
WBurke17

these are the only ones that are protected;

Kelso Jerusalem Cricket
Ammopelmatus kelsoensis
Point Conception Jerusalem Cricket
Ammopelmatus muwu
Coachella Valley Jerusalem Cricket
Stenopelmatus cahuilaensis
I will try to find pix and crossreference them.
cacoseraph

i will look for some genus keys or other sort of background info

Quote:

RANKING/STATUS: G1S1 (NatureServe – CNDDB); VU/B1+2bd (IUCN).

GENERAL DESCRIPTION: Jerusalem crickets are large, striking orthopteran insects. The genus Ammopelmatus differs from other genera of stenopelmatine crickets in the following characters: having vestigial or absent tibial spines on the apical dorsal margins of the caudal tibiae; even, broadly spathulate ringlets of 6 apical caudal calcars; median or presubapical spur on the ventral surface of the foretibiae absent; pronotum not expanded anteriorly.

DIAGNOSTIC CHARACTERS: Leg characters, such as the form of spines and spurs, are important for differentiating species in this genus. Both this species and Ammopelmatus muwu have short, spatulate apical tibial spurs and calcars; the fore tibia with only two small ventral spines; and the hind tibia with only one ventral spur and with reduced or no dorsal teeth. Ammopelmatus kelsoensis can be distinguished from A. muwu by its straighter apical spur on the internal margin of the fore tibia, and sharper first major tooth on the external margin of the hind tibia. The two species are widely separated geographically as well, with A. muwu occurring only at Point Conception in Santa Barbara County.
DISTRIBUTION: Restricted to the Kelso Dunes.

Ammopelmatus muwu is whitish in color; the heard is orange, and the abdomen has narrow black annular rings.

Ammopelmatus muwu can be distinguished from A. kelsoensis by the curved apical spur on the internal margin of the fore tibia, the hind tibia with the first tooth on the internal margin, and first major tooth on the external margin of the hind tibia short and blunt. John and Rentz (1987) studied the chromosomes of this species.
DISTRIBUTION: In spite of intensive collecting in southern California coastal dunes, this species has been collected only at the type locality at Point Conception.

Quote:
The Coachella Valley Jerusalem Cricket is known from the Snow Creek area from Fingal's Finger east to Windy Point, and remnants of sand dune habitat around the Palm Springs Airport. They occur in sandy to somewhat gravelly sandy soils and have been called an obligate sand species. They do not necessarily require active blow sand habitat but have been found in loose wind blown drift sands, dunes, and sand in vacant lots if native vegetation exists. They have been found associated with the roots of members of the sunflower family, including Ambrosia sp. and Encelia sp. (Weissman and Ballmer, pers. comm.).

Stenopelmatidae - Jerusalem Cricket

Stenopelmatus fuscus (not on the protected list?)

Natural History

The Jerusalem cricket spends most of its life underground. Its large, almost humanoid head supports the necessary muscles that assist the jaws in digging in the soil and feeding on living and dead plant materials. Like most crickets, this insect also produces sound, called drumming, by hitting its spiny legs against its body.

Jerusalem crickets complete a generation within a year, beginning with the hatching of eggs in the spring and the development of adults by fall.

I found black and gray ones at my grandparents house. They had black bodies with grey stripes and grey legs. Very cool. I only get the regular caramel colored ones by my house.

I've never seen a red one. It's beautiful!

(not there quite yet with the quoting)

Niños de la Tierra, i think the story goes that they scream like a child when you kill them...

Great find. I have only managed to hunt one Jerusalem cricket in my collection which was back when I was in 7th grade in 2005. Very nice.
