here is a tomato horn worm. i found it on our cherry tomato plants on
monday. it's huge, for a worm, about the size of my middle finger. i usually have no problem with squishing the (many) caterpillars i find on our plants (especially the cabbage family) by hand, but i was not ready to do that with this guy. it makes a pretty loud
cliking sounds as it chews the leaves off the tomato plants. those white things attached all over it are
brachonid wasp cocoons. we've been trying to attract this wasp to our garden by planting different flowers and generally creative a conducive habitat. the wasp
parasitizes all kinds of caterpillars, and lays its eggs inside them, eventually killing them. many conventional farmers spray pesticides to get rid of the tomato horn worm and others, but if you create conditions that will attract beneficial insects like this wasp, spraying is unnecessary. the system will balance itself out. pesticides kill not only the pests, but the
beneficials as well, so you become dependent on them.
in case you're interested in reading more about parasitic wasps and other beneficials,
here's an article i found online. there are many more, of course.

and this is our seed garlic, and onions in the background. our onions and garlic were beautiful this year.
