A warm calm night was ideal for the November mothing session at the Glenmaggie old bush block, and while setting up I noticed quite a few beetles flying up above. Hmm I thought, they could be a problem, and so it turned out to be. With the light shining they started to arrive, large and small, for example a Bess Beetle, Passalidae family, and a small elongated beetle in the Brentidae family, Cordus hospes. Bess beetles live in rotting logs and feed their larvae on masticated wood.
Then as the night wore on, small “beetles” came to the light in their hundreds, and it didn’t take long to realise that they were in fact bugs, not beetles, and one of the distinguishing features was their fragrance…. Many bugs emit a quite unpleasant smell, these weren’t so bad with an aroma vaguely tinged with eucalyptus. They were burrowing bugs in the Cydinae family, it was the first time I’d encountered them and I’m not particularly anxious to make their acquaintance in such numbers again….
Larvae of many of the Foresters, Zygaenidae family, feed on Hibbertia foliage. The block has plenty of Hibbertia obtusifolia, and on this night quite a number of Pollanisus sp. moths came in. They are a metallic green and quite eye catching, but unfortunately the wing scales are easily lost.
Another new moth settled near the edge of the sheet and at first I took it for a Geometrid, then saw the palpi and realised it was a Noctuid. It is Prorocopis euxantha, again a moth with a small number of state records.
