Micrathena schreibersi

$19.00 – $400.00

The spider genus Micrathena contains more than a hundred species, most of them Neotropical woodland orb-weavers.

The species are found in the Americas. Only three species occur in the eastern United States: females of M. gracilis (the Spined Micrathena) have five pairs of conical tubercles / spines on the abdomen, female M. mitrata have two short posterior pairs, and female M. sagittata (the Arrow-shaped Micrathena) have three pairs.

Species with extremely long spines evolved at least eight times in the Micrathena genus and likely function as anti-predator defenses.[1]

Orchard Orbweaver (Copy)

$19.00 – $400.00

Leucauge venusta, known as the orchard spider, is a long-jawed orbweaver spider that occurs from southern Canada to Colombia, along the East coast, reaching into the central US. The web is often oriented horizontally, with the spider hanging down in the center.

It is distinctively colored, with leaf-green legs and sides (which can sometimes vary to a dark green or even orange). The underside of its thorax is spotted with yellow and black, the top is silvery with brown and black streaks. The neon yellow, orange or red spots on the rear of the abdomen are variable in size among individuals and sometimes absent.

This species is parasitised by a wasp larva which attaches itself externally at the junction of the cephalothorax and abdomen.[1]
