Formicidae

The following are ants of the genus Camponotus: Carpenter ants. Some distinguishing characteristics include the smooth profile of the thorax towards the abdomen, lack of the metapleural gland orifice, antennae arising above the dorsal edge of the clypeus, and the absence of guard setae. One is a soldier ant, which is larger than worker ants, and the other is a winged alate, or reproductive individual. The soldiers are responsible for defense of the nest and the colony's territory. When mating season arrives, the male and female winged alates take to the air to mate. After mating, the male ant dies while the female ant discards her wings and burrows to found a new colony.

Common Name: Carpenter Ant

A useful key to the genera of Formicinae can be found here. The family containing ants is named "Formicidae" from the Latin name for ant (Formica). Methanoic acid is most commonly found in ant venom/stings, giving the acid the common name "Formic Acid." Ant societies are fascinating, and I highly recommend checking out books written or videos narrated by Edward O. Wilson, the leading expert on Formicidae. Here is one to get you started. Tip from gardening societies: To eliminate an ant colony in an environmentally friendly way, pour boiling water into the nest.

Back from Monterey

Well, there will be no official collection entries until I return to San Diego where my pinning and identifying equipment is, but here are some teaser live photos of insects and other animals spotted during the trip to Santa Cruz and Monterey. Those pictured below include a moth, a stone fly, two ants (I am 99% certain that that second ant is a winged reproductive individual, not a wasp), a beetle (fairly certain), and two bees, in addition to a banana slug and a salamander/newt - I'll wait for Phil to respond with an identification since he is the amphibian expert. Also, contrary to the popular myth, the underside of a banana slug does NOT numb the tongue. I very thoroughly tested this. The two bees are not common bumble bees or honey bees, so I look forward to keying them.







It ended up being quite a productive trip, since we found a caddisfly and a stonefly, both new ORDERS, not just new families. The stonefly, of family Plecoptera, is one of the older insect orders. They start their lives as aquatic nymphs, as do dragonflies. I will elaborate more on this order once I key the specimen to family - it will probably be one of my first entries after this hiatus!

Ants and Scale Insects

I went out to grab a picture of a possible relationship between ants, most likely Argentine, and scale insects. I am not certain what plant they are on, but it is definitely some kind of chaparral bush, probably Baccharis sarothroides. If all goes well, I will be doing volunteer research studying Argentine ants and their relationship with cotton aphids. Ants are in family Formicidae, and the scale insects, if I am correct that they are soft scale insects, are in family Coccidae.


In addition, I took a few pictures of the hundreds of caterpillars roaming the area - it seems like these caterpillars are the dominant organism out there. I grabbed a total of 6 to rear and confirm my hypothesis that they are Painted Tiger Moth larvae, as well as document any that have been parasitized.
