Saturday Five

Following in Dragonfly Woman's footsteps, and missing her alliteration by a day this week, here I am presenting five midsummer-nightly co-inhabitants of our backyard. This is just before the monsoon begins (we hope).


These little scarabs, Acoma sp. come to my porch light every year, but only the males. I have yet to find one of the flightless females. As with many other desert spp., the numbers are dwindling.


Temnochscheila sp. are predators of wood-boring beetles and usually associated with conifers. We had an old pine tree which I thought was the source of these beetles, but some years ago it died and was completely removed while the beetles are still going strong. Of course, the idea that our one pine tree, far removed from its normal habitat, would support this secondary guest (a predator of the tree's pests) was a little naive to begin with. This species seems to be a true desert inhabitant and quite independent of conifers.


This little wingless wasp had me wonder whether it was a mutillid or bradynobaenid but in fact its family Chyphotidae is not related to any of those. They just share the features that there females are wingless and their winged stin-gless males come into our house to buzz around the reading lights. This species impressed me because it is suspected to be a brood parasite of Solifugae, sun scorpions


 Kissing Bugs, the blood-sucking cone-noses  Triatoma rubida, are the only bugs that I always kill when I find them in our house. This year at least, they go into the freezer to be shipped off to a collector in Spain. Kissing bugs probably grow up in Packrat nests, but I have found nymphs in our dogs' beds, too. The adults are good fliers who are attracted to lights. Luckily their activity ends with the onset of the monsoon. Arizona has at least three species of Kissing Bugs but T. rubida is the only one I have collected around our house.


Midsummer night brought a tiny new moth, very delicate and pretty: Hileithia magualis, in the family Crambidae. I don't know its host plant. Its distribution is mostly southeastern with very few records west of Texas. (New Mexico and Arizona) A true Southern Belle.

  1. I've always been a nature-lover, but I've really overlooked our smaller co-inhabitants in this world. Going "insect-watching" might become my new favourite nature activity after reading your impressive blog! :)

  2. Your backyard insects looks wonderfully exotic.

  3. The best thing about insects is that there are always around. Even as a kid in Germany I knew where the pretty gold metallic Carabus auratus was hiding in its pupal chamber in the middle of winter, and here in Arizona there's always something to be observed and photographed.

  4. I feel rather lucky that we don't have Kissing Bugs here....or at least I don't think we do! The moth is stunning - one of the prettiest I've seen.

  5. Re kissing bugs (AKA vicious, pernicious, Chagas disease-spreading, sneaky, stalking, bed invading, blood-sucking assassin bugs):

    KILL THEM. KILL THEM ALL.

    I am a peace loving organic gardener who doesn't even kill aphids, but kissing bugs MUST BE INHUMED WITH EXTREME PREJUDICE.
