Snake-flies, alderflies, lacewings and scorpion flies in Essex Conwentzia pineticola British species, regarding C. pineticola as a mere form of this. It was not until recently that the existence of two species in Britain was published (Barnard 1978). Habitat and ecology The larvae are thought to be strictly associated with Scots Pine trees Pinus sylvestris and although adults may be beaten from deciduous frees there is usually a Scots pine hee somewhere nearby. There is some circumstantial evidence, however, to suggest that other species of Pinus may be utilised elsewhere in Britain. Threats The scarcity of Scots Pine trees in the county suggests that the loss of these from one area could be detrimental to the lacewing. Etymology From the genus Pinus = pine trees, in combination with the Latin verb cola, colere - hence, literally, "living in pines". to inhabit, Coniopteryx (Coniopteryx) tineiformis Curtis, 1834 National status; Common (Common) Predicted county status; Common/— Distribution A widespread species across the whole of Essex, and likely to be found in most if not all, Essex woodlands. Habitat and ecology The insect has been recorded from deciduous and mixed woodland, scrubland, parks and gardens. Adults seem to be associated, principally, with oak (Quercus), but several other species are recorded including ornamental species in parks and gardens. It comes readily to light traps. Threats None perceived. Etymology From the Latin forma = like/similar in combination with genus Tinea of the Lepidoptera, which at that date was a catch-all genus containing most of the micro-moths. Literally, Tike a tineid moth". Coniopteryx (Coniopteryx) borealis Tjeder, 1930 National status: Local (Common) Predicted county status: Common/— Distribution Evidently widespread in the western half of the county, but this may reflect recording effort rather than genuine scarcity in the east.
