Diaprepes Root Weevil

Dear Sarah,
Thanks for resending your images.  We are currently undergoing some technical difficulties.  This is a Diaprepes Root Weevil and according to BugGuide:  “Native to the Caribbean, adventive and established in so. US: so. & central FL (1964), so. TX (Cameron & Hidalgo Cos 2000, Corpus Christi 2005, Houston 2009;), so. CA (2005), LA (2008); further north in greenhouses.”  BugGuide also notes:  “highly polyphagous; larvae feed on roots, adults on foliage of citrus trees (esp. oranges in TX) and almost 300 other plant species” and “Major pest of citrus crops.”

Thanks so much, Daniel! I’d never seen anything looking like that before here in Southern California. (And I’m a native!) I guess I’ll kill any others I find since I do have citrus trees.

Prickly Pear Borer

Dear Emily,
This Caterpillar looks familiar to us, and we suspect we have previously identified it somewhere in our archives.  It reminds us of a Carpenter Moth Caterpillar in the family Cossidae, but we cannot substantiate that suspicion at this time.  Perhaps one of our readers will be able to assist in this identification.

Prickly Pear Borer

Update:  November 21, 2018
Thanks to a comment from Karl, we have identified this Prickly Pear Borer.  According to BugGuide other common names include:  “banded cactus borers (larvae of junctolineella and subumbrella) and blue cactus borers (larvae of dentata and prodenialis).”

Beautiful Cockroach Nymph

Dear Andy,
This is a Beautiful Cockroach nymph,
Ellipsidion australe, and though it is not a predatory species, it is also not a species that will infest homes.  According to the Brisbane Insect site:  “Not all cockroaches are ugly. This Austral Ellipsidion Cockroach looks beautiful. Its body is orange-brown to dark brown with white patterns. Its thorax is dark brown with a good looking yellow around the edge. The cockroach adult is winged, with brown forewings covered the black and white abdomen. Male and female look almost the same. Nymphs have the similar body structure except wingless. …They are very good runners.  This Cockroach  is active at day time, running openly on the leaves and flowers. Most other cockroaches are scavengers, they feed on almost everything. We are not exactly sure what this Austral Ellipsidion Cockroach feeds on, but they are always found on plants, seldom on the ground. They are believed feeding on pollen, honeydew and mould fungus.

This is a Snakefly larva, a harmless predator that is not normally found indoors, though we do not believe the fire was a factor in you finding it indoors.
