It is found that by feeding on Photinus males, Photuris females gain more than nutrients, and acquire defensive steroidal pyrones called lucibufagins, which are contained in Photinus but which photuris fireflies are unable to produce on their own.

The pretarsus of Phidippus audax (Hentz) consists of two claws flexibly articulated to a central claw lever which is flanked on either side by a curved plate of tenent setae. The claw apparatus…

The form and location of the scales of salticid spiders, as revealed by light and scanning electron microscopy, provide useful diagnostic characters for the separation of species, the assignment of…

Jumping spiders of the genus Phidippus tend to occupy waiting positions on plants during the day and often utilize an indirect route of access to attain a position from which sighted prey can be captured.
Learned avoidance of the large milkweed bug (Hemiptera, Lygaeidae, Oncopeltus fasciatus ) by jumping spiders (Araneae, Salticidae, Phidippus )

In the laboratory, Phidippus jumping spiders often attacked, but seldom fed upon nymphs and adult milkweed bugs when these were reared on milkweed seeds, but more satiated spiders were more discriminating in their choice of prey.
Shunning the night to elude the hunter: diurnal fireflies and the “femmes fatales”

Lucidota atra, a diurnal firefly, shares possession of defensive steroids (lucibufagins or LBGs) with nocturnal fireflies of the genus Photinus, and it is proposed that L. atra may have been prompted evolutionarily to become diurnal by the opportunity to avoid, thereby, being hunted by Photuris.

By use of this assay, Phidippus were shown to be sensitive to as little as 1 μg DHMA, an amount equivalent to less than 2% of the DHMA content ofC.
Structural Colors in Spiders
Structural colors are described and analyzed in theraphosid and salticid spiders. Some theraphosids are brightly blue: this is caused by special hairs with a lamellated wall that causes an…
